da Vinci: Body Proportion Theories
Middle schoolers investigate the validity of da Vinci's proportion theory by recording human measurements on scatter plots. In groups of three, they record each other's height and wingspan to create a Powerpoint presentation, chart, or...
Balanced Assessment
Plenty of Pentagons
Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Reflection of Light
Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.
Illustrative Mathematics
Reasoning about Multiplication
In critiquing someone else's theory, learners share insight into their own understanding of mathematical concepts. Fifth graders will explore the notion that products are always larger than their factors. While this statement is...
