Sum It Up! 

Here is a small strategy I used for our review day today.

In Advanced Functions we were reviewing average rates of change and instantaneous rates of change.

Instead of just doing problems from the book I organized the rate problems in 4 sets, polynomial, rational, trigonometric, and exponential/logarithmic functions. Each set had 3 problems.

I organized the class in groups of 3 and gave each group a set. They were to complete the problems and check the answers.

The kicker here was that the sum of the 3 answers in a set was written on the board.

If the group got all questions correct their sum of their answers would match correctly. But…… If one was wrong they had to check all solutions and decide which needed fixing.

First, this small change made all groups work more carefully than usual. And second, when they had to double back, you could see them rationalizing which answers “had” to be correct and which answers were “toss ups”.

It was a great tool for students to self assess and evaluate their own readiness.

After each group completed a set they would swap with another group… Eventually completing all sets.

Final Assignment – Estimation Challenge

For our final activity I started the off with this……

we filled in too high, too low, and best guesses! Then we checked the answer…..

Completing this challenge got the students pumped and hooked into doing some math on our very last days of class (especially with some students exempted from the final exam). Our final assignment is to …

We got out the iPads and I let the kids work….. here is what a few came up with:

A lot of kids did water filling or post it note covering estimates. Some kids ended up making an all-out 3 Act math problem.

A 3- act task in Explain Everything:

How many post-its will cover this triangular wall:

Act 1: She put a photo and a small video in Explain Everything to start us off.

Act 2: She provided us with a little more info after we made some guesses.

Act 3: Made a time lapse video and provided a screen shot with the answer

A fun last few days….and I’ve got some new estimates for class next year.

3 Act Math – Ground Cover

With inspiration from Dan Meyer through Kyle Pearce, I created a Three-Act Problem. My grade 11 class just finished finding side lengths and angles in right triangles using the primary trigonometric ratios, and we’re moving on to solving problems! In the spirit of solving problems…..here is a Three Act Problem.

Ground Cover

Act 1: Video

Act 2: Pictures

Sod Dimensions

Garden Measurments

Act 3: Video

IPads and Apple TV in Math

This will be my first time using Apple TV in math class. The idea for the Apple TV today will be to share student work.
Here is our run down:
1. Check connectivity for internet in our classroom. Visit here to get the Smart Notebook file we will be using. —- If internet is unavailable we will use wifi from goodreader app.
2. Download lesson file and gsp file.
—-First practice switching between apps, and taking screen shots.
3. Connect to jmss ipad network which will allow us to us Apple TV.
4. In groups, discuss and answer questions to first slide about the effect of b. use the gsp sketch. Record results on paper or digitally in the Smart Notebook app. Do again for next slide.
5. Students can graph the exponential in their app…..once all groups are finished….i will pick a group to connect to the Apple TV, to explain and show their work.
6. I will do the next example….as a demonstration….students will complete the next few slides as I circulate.
When students get to the Communication Slide have them take a screenshot of the page. Open the Explain Everything app……load the screenshot. Students are to answer the communication question while recording their voice and notes. They are to upload their work to the class dropbox folder or copy it to my ipad. This will be their exit question for the day.
