KAS Math Standard: KY.1.OA.8

Determine the unknown whole number in an addition or subtraction equation relating three whole numbers.

Gr 1-4

Gr 1-4

Back to School Math Worksheets

In these math problems, the solution is already given. But another number is missing!

Gr 1-6

Spring Math Worksheets: Multiplication and Division

Sets of multiplication and division practice problems. But the unknown isn’t where you expect it to be!

Gr 1, 3, 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 1-4

Math Curiosity: Magic Triangles

Can you make each side of this triangle add up to 9 using the digits 1-6?

Gr 1, 2, 3, 4, 8

How Many Ways: Fraction Addition 234

How many different ways can you make this fraction addition statement true using only the digits one through nine?

Gr 1, 3, 4, 5, 7

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 1, 2, 3, 4, 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 1-4

Math Curiosity: Goldbach’s Conjecture

Can any even number be written as the sum of two primes? Goldbach thought so, but we haven’t proven it… yet!

Gr 1-5

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 1, 2, 3, 4, 7

How Many Ways: Fraction Equivalence

How many different ways can you make this math statement true using only the digits one through nine?

Gr 1, 2, 3, 4, 6

How Many Ways: Times Equals Minus

How many different ways can you make this math statement true using only the digits one through nine?

Gr 1, 2, 3, 4, 6, 7

Math Curiosity: Waring’s Conjecture

So, can you write every odd (greater than 3) as the sum of three primes?

Gr 1-5
