It’s time to pretend to be a detective and find these mystery numbers! Use the clues to figure out which number belongs on each card! This  Math Mysteries – FUN Addition and Subtraction Math Problems is sure to make math fun.

Math Mysteries Worksheets

There are two sets of these cards – one for addition under 10 and one for addition under 20. Each card includes a clue based on even and odd numbers and 2 clues that include either addition or subtraction.

There is also a recording sheet included for use with a group of kids.

What Number Am I

If you’re going to use the set in a group, I’d recommend laminating the cards. This way kids can use dry erase markers on the cards but they can still be reused. Have them write their final answer on a recording sheet.

Otherwise, the cards can be used on plain paper for just one child.

What Number Am I

Math Mystery

These cards rely on logic to figure out the answer, but the answer can be found purely through using math.

Go through each clue and eliminate as many numbers as possible until the final number is revealed.

The first clue is always indicating whether the number is even or odd. So start by crossing off any number that is excluded.

Keep moving through the cards until there is just one number left. That is the mystery number!

My kids enjoyed acting like detectives while doing their math (and I totally keep magnifying glasses on hand just for occasions like this!)
