Geometry Image: University Ave
What odd and interesting shapes can your students find in this geometric image?
Depth and Complexity: Patterns and Quadrilaterals
For TeachersWhy just “identifying patterns” isn’t deep enough.
Racetrack – Race Around A Graph
How fast do you get your mathematical car going without crashing?
How Many Ways: Fraction Subtraction Equals 1/2
How many different ways can you make this math statement true using only the digits zero through nine?
Looping Grid Art
Pick a few numbers, draw some corresponding lines on grid paper, and you’ll end up with some interesting, looping math-y art!
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?
Addition: 3 Digits Plus 2 Digits (Multiple Solutions)
Typical practice problems don’t move students up Bloom’s Taxonomy. With this framework, you’ll see kids stop and really think about how to approach multi-digit addition.
Writing A Story About Fraction Equivalence
When fractions take on a new denominator, it’s as if they’re wearing a disguise – same value, new look. So let’s write a story about fraction equivalence starring a fraction who needs to fit in with a new group.
Intersecting Angles and Streets
There can never be just one angle.
Why Is Our Calendar So Weird!?
Why are there 12 months? Why don’t weeks fit into months evenly? Why don’t weeks fit into the year evenly? What’s going on with the calendar!
The Angles of a Triangle
Why tell a kid the rules of a triangle when they can discover them!?
Math Curiosity: Waring’s Conjecture
So, can you write every odd (greater than 3) as the sum of three primes?
