Mow A Lawn
How long would it take to mow a very large lawn with a push-mower?
What’s In My Brain: Trapezoids or Not?
Which are trapezoids and which are not?
Same Perimeter, Different Area For Rectangles
Can two rectangles have the same perimeter but… different areas!?
Intersecting Angles and Streets
There can never be just one angle.
The Angles of a Triangle
Why tell a kid the rules of a triangle when they can discover them!?
Lines, Line Segments, Rays, and Infinity!
A lesson about lines, line segments, and rays that avoids dull memorization. Instead, we ponder this delightful question: Which is longer, a ray or a line? Then, kids consider what these different geometric concepts would think about each other.
Deducing the Area of Triangles
Using patterns, students try to deduce where that area formula came from.
How Many Students Can Fit On The Playground?
So… just how many kids could we cram onto the playground?
