Playful Math for Middle & High School

As our children (and their parents!) play around with mathematical ideas and the relationships between them, we develop deep understanding that is strong enough to support future learning.

Algebra 2 Foldables Made By My Students: "Their assignment was to create 3 interactive notebook pages over 3 topics we studied this year. Please note that these were all produced by my students, and there are several small mistakes sprinkled throughout them. If I do this project again, I think I will have students submit a rough draft for me to review before they complete their final drafts...."

Angle Sum Theorem: It's not a rigorous proof, but it's a start. Helps students internalize the principle that the angles of a triangle = a straight line.

What a cool set of first-day activities! Designed for Algebra II, but could easily be adjusted for other classes.

This is a game I play with my students to practice corresponding angles, alt. interior, alt. exterior, supplementary, same side interior. They must place feet in the type of angles I call out. (Got from YouTube video)

Algebra Taboo: My co-teacher and I went through all the Integrated Algebra regents given since 2008 and pulled out any words that it’s possible a student might not know. I also went through my own lessons and pulled out any vocabulary I had given them. Below is the pdf for printing your own...

Algebra Taboo | The Roots of the Equation

Ive seen a few variations of using the famous game Battleship in math class.  Who among us hasnt used it (or at least the concept) when reinforcing graphing coordinate pairs? Taking it in a slightly more advanced direction, lets make a 4 quadrant Battleship grid.  And lets require kids to write equations in slope-intercept form, graph them, and develop a strategy for this process. (Putting equations in point-slope would be a great substitute if you want one.) P1

i is a number: Slope-Intercept Form Battleship

One of the great unsolved problems of antiquity was to trisect any angle using only the basic tools of Euclidean geometry: an unmarked straight-edge and a compass. Like the alchemist’s dream of turning lead into gold, this proved to be an impossible task. If you want to trisect an angle, you have to “cheat.”
