Number Mysteries for Math Detectives!

My first graders just started adding two digit numbers, but some of them still need a little practice with place value.  I made a fun center that focuses on ten more/ten less and one more/one less.  It was such good practice and so much fun that I decided to share it!

Students pick a card, write their number in the center, and then fill in the missing numbers around it.  I made cards in both color and black and white.  There are a total of 30 different cards.

Super easy to prep and great practice!  That is the way uh-hu, uh-hu I like it!  :)

I hope some of your little math detectives can get some good out of this.  Click here to download this freebie!
