Who can get to 100 first in this simple, but delightful, math game?

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?

How Many Ways: Add to 170

Four blanks, ten digits, one target. Students hunt for every pair of two-digit numbers that adds to 170 without repeating a digit, then work out why there are only four.

Evens and Odds – Addition and Subtraction

When we’re adding and subtracting, do evens make odds into evens? Do odds make evens odd? Which one has… more power!?

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.

Subtraction: 3 Digits Minus 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 subtraction.

Place Value (Beyond Base 10)

Place value is something we cover in elementary school. It seems simple, but I’d wager that very few adults really understand the topic. 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?
