TEKS Math Standard: 2.4.B

add up to four two-digit numbers and subtract two-digit numbers using mental strategies and algorithms based on knowledge of place value and properties of operations

Gr 1-4

Gr 1-4

Spring Math Worksheets: Addition and Subtraction

Four sets of 2-digit and 3-digit addition and subtraction practice. But the unknown isn’t where you expect it to be!

Gr 2-5

Game: Number Scrabble

What if we played Tic-Tac-Toe with numbers and instead of three-in-a-row, we add up to 15? Well… then we’d have Number Scrabble!

Gr 1-6

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.

Gr 3-6

Subtraction: 3 Digits Minus 2 Digits (Single Solution)

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.

Gr 3-6

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.

Gr 3-6

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!?

Gr 3-4

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?

Gr 4-5

Math Curiosity: Four Squares

Every positive integer can be written as the sum of (at most) four perfect squares!

Gr 1, 2, 3, 4, 8

Math Curiosity: Primes and Squares

Can any perfect square be written as the sum of two primes?

Gr 2-4

Math Curiosity: Palindromic Number Conjecture

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

Gr 1-4

The Game of 100

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