A Lunar Survival Mission
A favorite of mine! This task is delightfully complex and ambiguous, forcing students to make choices without enough information and with no right answer. How will they survive on the moon for three days?
What If There Were No Hundreds Place?
Imagine a world with no hundreds place. We’d have to call it ten tens instead. But then, what would we call the thousands place? How would we read 9999? What if we added one more?
Fraction Ordering Tournament
Which set of fractions would be the trickiest to order from least to greatest? Let’s have a tournament!
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.
Same Perimeter, Different Area For Rectangles
Can two rectangles have the same perimeter but… different areas!?
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?
The Angles of a Triangle
Why tell a kid the rules of a triangle when they can discover them!?
Grouping Quadrilaterals In A Hierarchy
Can we classify quadrilaterals like we classify living things?
What Do Mean and Median Mean?
When will mean and median give us different results?
Depth and Complexity: 👄 Language of the Discipline
Imagine a construction worker who doesn’t know the name of a screwdriver or a doctor who can’t remember what to call your neck. It’s pretty hard to communicate well without knowing the 👄 Language of the Discipline!
Discovering Pi With Sticky Notes
Pi is mysterious and strange! Why not let students discover it on their own?
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.
