## Appetizers:

### Estimation180

Estimation180 is great for warm ups but even better for getting students to practice predicting their answer which allows them to decide if their answer they calculate makes sense. Here is an example:

### What is the value of pennies in the glass?

Questions we ask to get students thinking of reasonableness of their answers. Give an estimate that is too low. Give an estimate that is too high Give an estimate that is just right.

### Would You Rather

ASKING STUDENTS TO CHOOSE THEIR OWN PATH AND JUSTIFY IT!

## Main Course

### Engaging Math Problems vs. Standard Math Problems

#### 3-Act Math Problems

Original concept from Dan Meyer – Read about it – The Three Acts of a Mathematical Story

Here is the Corner to Corner  3 – Act Math Task – http://www.101qs.com/2998-corner-to-corner  Here is another…

### Act 1: The Water Balloon

Did you wonder when the balloon will blow? Give an answer too high, too low, just right.

### Act 3:

Here is the same problem from a standard Math problem from grade 9

A water balloon is filled at a rate of 0.22L/s If a standard balloon will hold about 14L of water, how long will it take until it bursts?

### Desmos.com

Online free graphing calculator – enough said!

### Desmos Function Art Assignment

Grade 11s use their knowledge of functions to draw a picture.

### Explain Everything as a delivery tool

We began many classes by grabbing an Explain Everything file from our Google Drive. Here is a picture of that file. Here are some more examples of using Explain everything as a “digital worksheet”     or or
