3 Act Problems & Lessons

Below are Three - Act math tasks and lessons I use with my classes. If you have never taught a lesson like these I suggest you start with Dan Meyer's post. Feel free to use and edit these lessons. Click away and read about each lesson. 

Energy Bites

A yummy lesson where students use volume of cylinders and spheres to determine how many energy bites are made from a recipe.

Pentomino Puzzles

A Hands-on activity is blended with interactive technology. Students begin with puzzles but ultimately create algebraic expressions and solve equations.

Pumpkin Timebomb

Pumpkin Timebomb

This fall themed activity asks students to predict how many rubber bands will implode a pumpkin. Use data collected from over 120 exploded pumpkins and create scatterplots to make predictions.

Reading Relationships

Reading Relationships

Promote literacy while learning math! Students calculate and track over time their words/min reading rate. Students will also explore the relationship between fast reading and comprehension.

Trashketball [3 Day lesson]

Trashketball [3 Day lesson]

In this multi-strand lesson students will use estimate and calculate how many paper balls fit in a bucket. They then will race to see who can make more shots into the bucket in a minute.

Make it Parallel

Make it Parallel

Students explore properties of parallel lines & transversals. They will create parallel lines on the floor or outside with chalk, and finally use Explain Everything to answer problems.

Dora to the Rescue

Dora to the Rescue

Finally teach collecting like terms and the distributive property with context! Find the perimeter and area of a counter top using only Doras!

Is Lego Gender Biased?
