Crossing Every Bridge Exactly Once (aka Eulerian Paths)
How can you cross each bridge in this city exactly once?
Math Curiosity: Magic Triangles
Can you make each side of this triangle add up to 9 using the digits 1-6?
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.
Rounding Numbers (But Not To 10)
What could we possibly do to make rounding more interesting for students who already get it? In this series, students consider how they might round to values other than “the nearest 10.” How, for example, do we round to the nearest 9? 7? 15?
Fractals: Sierpinski’s Triangle
What if this triangle pattern just kept repeating… forever!?
Math Curiosity: Twin Primes
What do you call two prime numbers who are very close together?
Create A Civilization Introduction
Your students build a civilization from scratch — rivers, flags, calendars, currency, government. Social studies, science, and writing woven into one year-long project.
Furnishing A Hotel
Design and furnish hotel rooms on a budget. Real math, real constraints, real decisions. Then pitch your hotel to investors.
A Grid-Based Fraction Project
You’ve got 60 spaces on a grid to create an amusement park, a house, a farm, or whatever you’d like. Divide it into seven pieces, order it by size, combine into two halves, and more in this fraction project.
