Perfect day for pennies

It has been a long week before vacation and I had planned on doing an activity with pennies in Algebra I.  It went well.  I asked the kids to bring in pennies.  We were going to look at the minted date and organize them by date, make a dot plot of them, and then see what we were going to notice some things.  I had the students predict the year that the most would be minted and predict the amount of pennies we were sorting as a class.

Here are some pictures: action shot: sorting the pennies

 Period 1- partial picture
Period 2 - picture
Period 1 - dot plot (The most popular was the year 2000.  We thought maybe they made more that year because of the year 2000?  We sorted 301 pennies.)
Period 2 - dot plot - I drew a line this time to be a little more even.  (The most popular year was 2013.   We sorted 292 pennies.)

Persevering with Polynomial Rollercoasters

I assigned a new project this year: Rollercoaster Project  I found it online but forget where to give you credit (sorry).  It looked really cool, so I thought I would give it a try. 

It is two parts.  First, it asks students to answer about 17 questions on rollercoasters and the behaviors of the polynomial.  It was pretty straightforward.

The second part asks them to design their own with some specifications like it has to start at 250 feet up, last for a least 4 minutes, have a double root, go underground, have at least one real root, and at least one (two) imaginary roots. 

I originally had this due right before Thanksgiving but we had a test then too and kids were focused on that, as they should be.  Also, I had only had 2 out of 48 kids come for extra help with questions on it and their questions were showing me their struggles.  I thought, uh oh, what had I done.  Is this too hard for them?  Is this too much for them?  So, I decided to extend the deadline to this Thursday.  I had students come for extra help today and they were doing it!  And, they were sticking with it.  They were getting frustrated at points, but they were working together and helping each other find their mistakes. 

Oh, and the thing that made this wonderful was desmos.com.  The kids love the site.  We figured out how to adjust the axes so we could see the rollercoaster they were graphing.  They started in factored form.  Then, they needed to figure out how to get their y-intercept to be 250.  They graphed it.  It looked good.  It looked like what they intended it to look.  However, I wanted it in standard form as well.  And, this is where they were running into trouble.  They did a lot of work and then entered it into desmos as a different colored line and they weren't the same.  Ugh!  Some had the graph as x<0, why?  how come?  Oh, they wrote their factored form as (x+2) etc.  So, she needed to change her signs.  Others found small sign errors or dropped x's or incorrect multiplication.  But, they stuck with it.  They persevered and let me tell you....they were excited when they finally saw their green line and their purple line become the same line on desmos!  So cool.  They could see it worked!  And, this was all AFTER school! 

It was fun to work with them.  However, I am not looking forward to grading 48 projects. 

My Price Is Right Flop

I have a small group of juniors and seniors (5-8 on any given day) and I am doing project based math learning with them.  I like teaching this way, but I have to be more flexible.  I am not good at estimating the time it will take them, so I have to be okay with things finishing early (and have something else on hand) or things running over to the next class.

On Monday, we looked at the letters in Wheel of Fortune.  We read small excerpts of books and tallied the letters and found the percents and the top 10 letters and bottom 5 letters.  The kids did well with this.  It took a long time.

Today, we looked at the games on Price Is Right.  We talked about what they knew about Price Is Right, not much.  I showed them a youtube video of the C'mon down to contestants row.  I only had 5 kids in class today but we played contestant's row anyways.  I put all their names in a bucket and picked them and order was important.  I gave them little white boards and one by one they bid on 3 different items.  They were starting to get it but struggled a bit with the idea of "closest without going over" and why $1 over another bid would be a good strategy.

Then, I asked the school to unblock some game sites and we played three games - Price Is Right Strategies.  I wanted them to play The Clock Game 10 times and record their wins and losses.  Then, I wanted them to play Plinko and record the money they won.  Next, play Cliffhanger and record wins and losses.  I wanted them to play each 10 times so it was be easy to figure out their percent of wins and losses.  You would have thought I told them to run 10 miles.  They were so competitive and wanted to quit when they weren't winning.  "This stupid.  I rather take a quiz."  They were all having a grumpy day and feeding off each other.  It wasn't pretty.

My intention was to have them play each 10 times, then tell them some strategies and play them 10 more times and see if they did better.  We didn't get this far.  I had lost them.  I told them the strategies but at this point they didn't care. 

I told some different students who stayed after for extra help and they thought it sounded wonderful. 

I will see this class again on Friday and am just ready to give them worksheets.  They want Chinese food.  It will have to be somewhere in between worksheets and Chinese food.  I was thinking Press Your Luck, but now I am not sure.

#MTBoS - Sharing is Caring

Here is the challenge:  Mission 8: Sharing is Caring in the MTBoS

And, I love Care Bears.

Plus, I am already doing this, so it is a quick, easy Sunday blog.  I think this will be the 3rd or maybe 4th of the 8 missions.  I had good intentions and thought about all of them, but didn't get to some of them.

I love sharing stuff I find.  I email it out to colleagues and retweet stuff on twitter.  I feel like I am my colleagues' own personal RSS feeder. 

I just shared this with Kathy, a stats teacher - love it.  I saw Fawn tweet it today:  Stats Joke

I shared the Simpson's math with Tim because he had heard about it somewhere. I told him I had an article:  Simpson's math

I am always sharing @yummymath stuff.  I love everything Brian and Company does there because it is so accessible to the students and well done.

I share Calc stuff with Sue and Chris - our Calc teachers - stuff like this: Chain Rule

I shared Justin's logic google doc with our Geometry teachers.

I am spreading the word about all stuff Dan Meyer, Mathalicious, and Math Munch to name a few.

And, I share my blog :)

#MTBoS - A Day in the Life of This Teacher

Also known as, If You Give a Moose a Muffin. 

Instead of the hamster wheel, I think of this book because one thing just leads to another.  I knew I was going to blog about today, so I wrote everything down because I don't remember anything.  It is long and detailed.  You will get a gluten free brownie at the end if you read all the way through.  Thanks!

5:30 am wake up and shower - I put my clothes out the night before and I knew I have a full day, so I pulled out the hedgehog sweater: 

5:45 am get Boy #4 up to shower, I make my breakfast and lunch.  I knock over the cat's water bowl and clean it up (it is the only way the floor gets washed).  Someone ate my tuna, so I have to make some more to have with my salad.  While I eat my breakfast at the computer, I check my home email, school email, Facebook, Twitter, and news.  I find a lesson on Minimum wage from Free Tech for teachers.  I add it to my Futures lesson plan for later.  I read an email about a bake sale I need to bake for for Sunday.  I answer a few emails.  I need to remember to sign my emails correctly - Mrs. F, Coach, or Jennifer.  I tweet about my upcoming blog post tonight.  I read Wendy's blog post on her day and wonder if my day will be that crazy, too.  I think it ended up being as crazy.  I find Andrew Busch's lesson on systems with Light Bulbs - systems.  I put this in my google doc for later, too.  It's a good morning, two new ideas for lessons!  I quickly read the Alg2Chat twitter chat on storify to catch up.

6 am: Boy 4 wakes up Boy #3 to get in the shower.  Boy 3 is a freshmen at my high school and Boy 4 goes to 7th grade in the school right next door, so we all drive together.  They shower, make their own breakfast and their own lunch.
6:45 - head to school
6:50 - get to school (yep, school is 1 mile away)
Get my day ready - I teach all 5 class periods in a row today.  I put desks in order, open the shades, write date on the board, empty the pencil sharpener.  I have one student for extra help, so I answer her question.  My 9th grader comes into my class with me to hang out for a bit before school.  Today is a B day and all my graded assignments are due.  So, I need to have all the old graded ones ready to hand back and all the new ones ready to hand out for each class.  I get my Candy Lab ready for my 2nd period class because it isn't in my room and I need to make sure I take everything with me. 
7:20 first bell rings and I am ready to go

7:25 - Period 6 (1st block) - Accelerated Algebra 2 - 20 kids, preparing for a quiz for next class.  Day started with a compliment on my "hedgehog" sweater.  Made me smile :)  Collect the assignment sheets, go over the homework, and then we play a review game called "Risk Your Knowledge of Polys": Risk Polys Some of the math symbols don't come through.  Anyways, the kids loved it.  They all start with a recording sheet and 100 points.  They can always wager at least 100 points even if 0 or negative points.  If they have more, they can wager up to what they have.  If they get it right, they get the points, if not, they lose the points.  They get to view the question first and then place the wager, then do the problem.  As a teacher, it is great to walk around the room and see how confident they are.  On long division, I said I noticed class was about 50:50 on low/high bids.  One student said she bid low because she knows she makes stupid mistakes.  Another said she bid low because she is just cautious but was getting everything right.  I said, "Maybe I should make up a quiz that is bid your own points and you have to bid something on everyone."  They seemed to like the idea, so I will give it some thought.  One student asked if he could bid negative and get it wrong :)  Struggled with long division, given zeros, write the polynomial, and factoring two cubes.

8:30 - Period 7 (2nd block) - Futures - this is a class of 5 seniors and 3 juniors who can't learn in the regular classroom anymore.  They are at the other end of the school, so it is a long walk down, but I enjoy getting away from my little corner of the world.  It is my first time teaching them and I am enjoying it.  I definitely have to be more flexible because they are coming from all different backgrounds and I never know who I will have.  We have been working on systems - doing lots of different activities but I haven't really called them systems or been too formal with it.  I was planning on doing the Candy Lab today and had everything ready.  It is 3 different types of candies in a bag and they need to figure out how many of each.  I bring a scale, give them the total number of candies in the bag and 1 hint.  I showed up and there were only 3 kids.  Nope, not doing the Candy Lab.  It will wait until block period tomorrow.  Good thing I am flexible and prepared.  I had copied YummyMath's concession stand systems of equations.  I told them there were lots of ways to solve them.  One girl said, "Let's do it the easy way."  I asked, "And, do you know the easy way?"  She said, "No, but you do."  She is pretty quick.  So, we went through this and they did well.  The last problem gave them the 2 equations and used B and D for variables and asked them to make up a story.  They call used beer and doughnuts. 

9:35 - Stop for a bathroom break.  Forget to eat my snack.  Period 1 (3rd block) - Accelerated Algebra I - freshmen.  We are doing a flipped classroom for systems of equations and inequalities.  The first day they went to www.edmodo.com and it linked them to www.blendspace.com where my colleague posted a video of her teaching solving by graphing and solving using substitution.  They were to watch each video, answer quiz questions on paper, and then enter the answers onto the blendspace.  The quiz would be collected the next day for a homework completion grade.  Last night, they watched the video on elimination.  Yesterday, we did a couple of activities in class.  Today, I collected the homework and had them work on 4 challenging substitution problems.  They understand the process but the numbers get in the way.  These problems had fractions and negatives, gasp.  I said A negative can do so much damage.  We have negative collateral.  They would just drop a negative sign.  They would not distribute the negative through as neg times neg is positive.  Ugh!  Then, we did the same YummyMath Concession Stand activity.  They picked up on it more quickly than the Future's kids.  When they got to the last question with the B and D, they did Burgers and Drinks.  So innocent.

10:40 - grab my cereal bar finally.  I was starving.  Period 2 (4th block) - Another Accelerated Algebra I class of freshmen.  I see this class for an hour, then they go to lunch for 30 minutes and come back for 20 minutes.  It is considered block period.  It runs similar to the last class but a bit quicker because I am more smooth with my transitions and passing out of papers, etc.  As they are working, I check off both classes of collected homework in my grade book.  I also take a peek at the attendance for next period because I am hoping all 28 will be here for my quiz, but nope, 2 kids are absent, bummer.  After lunch, we switch gears.  We are working on a MAP example of correlation coefficients.  Last block they worked on it individually.  This time they worked in groups to share their methods and determine the best method to find a correlation coefficient (not just r on the calc).  They had some good conversations and good sharing with the class.

11:50 - we break for lunch.  My colleague brought me my favorite - Doritoes and Hershey Bars for a late birthday snack.  A friend commented on my "porcupine" sweater.  I corrected her :)  

12:40 - Last period Period 3 (5th block) - Accelerated Algebra II - thank goodness they are quizzing, so I arrange my desks into rows.  As the kids come in, I hear the drama kids talking about their upcoming musical and they are doing an Ugly Sweater Day as their psych up.  I hope they don't think I am taking part.  While they are quizzing, I start to get my math teams ready for tomorrow's math league competition.  I can only try to put them together but I really have to wait and see who actually shows up for the bus before I finalize the teams.  Tomorrow is a crazy day because we have the math meet from 2-6 pm and then I have my Cross country team's banquet at school at 5:30 (yes, I will be running in late).  So, I have to go to school tomorrow ready for the math meet and the banquet and will be there until at least 9 pm tomorrow night.  I also take a stab at starting the Algebra I's upcoming quiz.  In alg 2, the kids are taking a non-calculator part and a calculator part, so I have to keep track of who has which part and then staple them together when they come in. 

1:50 - school day is done, let the fun begin.  9 kids come in for my extra help day.  I have some here for their quiz the next day and some for the rollercoaster project I assigned.  It is the first time I assigned it and it is giving us quite some trouble.  I will have to spend more time with it.  They persevered until about 3:10 when I had to leave.  As I was walking out, I saw Son #3 and 2 friends waiting for a ride home.

3:15 home and dog is waiting to go for a run.  It is 45 degrees, but out we go for a 3 mile run. 
4 pm home and defrost chicken chili for dinner and start to warm it up
Smell my school bag and it smells horrible.  I search and find a super rotten banana, disgusting.
4:05, upstairs to watch the start of Ellen, do some stretches, abs, and weights, then get changed and figure out clothes for tomorrow's school day and for the banquet tomorrow night
4:30 - empty out smelly school bag and find $13 I thought I already repaid to a teacher, I guess not.  This reminds me that I left a banana in my XC backpack.  Good, I caught it before it was too late.  Throw the bag in washer. 
4:45 - sit on couch to watch news with my husband as I grade the 26 quizzes.  Kids get an average of 87, pretty good. 
6 pm - eat dinner - chicken chili
6:10 - sign 60 cross country certificates, answer phone call from newspaper guy asking me questions about my runner that ran at All States this past Saturday, put certificates in order of my speech (10 page speech).
6:30 - put all runners' times into page protectors for tomorrow night, add to my bag of stuff for tomorrow
6:45 - check email - realize I forgot to upload blendspace link to edmodo as 3 students sent me emails.  Upload it.
6:48 - send 4 pictures to school email so I can finally sit down and blog.  And, 1/2 hour later, I am done.

7:20 - my day is done, that is until Boy #3 finally asks me for help on his math homework.

PS - I am too tired to proofread this.  So, here's to hoping I got it right and here is your brownie.....

Angry Birds Rocked It!

I just had my kids do this Angry Birds Project.  (I loved that there were 5 editions.  Although one student wrote "2nd addition".)  This teacher did it with her 8th graders and mine are sophomores in Accelerated Algebra 2, so I was a little worried it might be too easy.  We are going so fast through this material with the new common core, I don't feel I have any time for big projects in class, so I assigned it for out of class.  I gave them a month and made it due after we finished quadratics, so they would have everything at their disposal. 

I also liked the idea of an "old fashioned" poster.  I had them work in groups of four and each take a bird and do their bird's graph and then put it together on one graph.  The posters were great.  The kids used their calculators to graph and solve.  They used Desmos.  They used calculators and did linear regression.  They used the quadratic formula.  There was all sorts of stuff being done.  Too much for just the front of the posters, lots had to go on the back.  Now I just have to figure out how to get them all up on my walls.

Our grades were due on this past Monday so I did a ton of grading over the weekend.  I felt refreshed being all caught up when I came to school on Monday only to remember I would be collecting these projects.  Yesterday was a professional development day, so I came in an hour early and left an hour late because I was so excited to see how the kids did.  The projects were awesome.  I got the 12 projects graded!  I told the students not to ever expect that again :) 

Even though they were old fashioned posters, the kids got in the technology.  One group photoshopped the angry birds and two pigs into www.desmos.com !  Cool! 

Here it is:

Here is another group.  They even added glitter to their title.  I love glitter :)  The group below cut out their little angry birds and pigs and glued them.


 

Multiplying with Paint Arrays

I teach HS math but I tutor a young man in 5th grade.  It is nice to be able to see what is coming up the pipeline and how they are teaching math.  He is struggling with multiplication and we are working on it.  I thought if he saw arrays it might help.  So, this just came to me in the middle of a tutoring session, let's paint some. 

I grabbed a paper plate, some paint, and pencils and we dabbed the eraser end in the paint to make little circles and create arrays.

I started by making a 3x4 and asked him what it equaled.  I made one more.  Then, I asked him to try a couple.  They I said, make on that equals 35 and he tried.  He was a little off but he was learning.  We tried another when I gave him the total.  I told him to use one that had a side of seven.  It was fun and I think he liked it. 

Here are some pictures.  Paint doesn't really erase well, so he is covering up one of his mistakes.
