Fractions: Decompose and Recompose
What if we took a fraction apart, then took those pieces apart, then recombined them, and then recombined those, arriving back to the original fraction?
Create Your Own Operation
The commutative and associative properties are a whole lot more interesting when you apply them to a mathematical operation that you created!

I sure didn’t until I worked with non-base-10 number systems in college. Your students can get a taste of this mind-boggling experience by imagining what it would be like if we didn’t have the number 9. What would each digit represent then?
The Angles of a Triangle
Why tell a kid the rules of a triangle when they can discover them!?

Can we classify quadrilaterals like we classify living things?
Deducing the Area of Triangles
Using patterns, students try to deduce where that area formula came from.
