Alabama Math Standard: 3.NBT.A.11

Use various strategies to add and subtract fluently within 1000.

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.

Broken Calculator: 2-Digit Addition

This calculator adds two-digit numbers wrong, the same way every time. Crack the rule, then predict its next mistake.

Broken Calculator: 2-Digit Subtraction

This calculator gets subtraction wrong the same way every time. Can your students crack its broken rule?

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.

Math Curiosity: Palindromic Number Conjecture

Using this one weird trick, it seems that you can turn any number into a palindrome!
