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!

This will be great practice for my second graders...we did fine on the hundreds chart. Now they are supposed to use numbers in the thousands...and some will add all kinds of numbers! This will be great to show them it is still +10/-10! Thank you!

Hi Suzy Q! My kids do silly stuff like that too! Sometimes it takes a while before it finally clicks. Thanks for visiting my blog! :)

P.S. I TOTALLY hate the exclamation point on this font! It looks like a lowercase l. I always think I have typos and it is just that darn exclamation point!!!! :( Sorry just had to vent! :)

I am ready to do this tomorrow for our warm up. I will fill the middle boxes in on one side which we will check together and then copy the same without anything in the middle and let them pick their own challenges and then exchange papers with a partner. They have to stay with the partner and check the work so they need to know their own answers. I think they will have a great time.

What a fun idea! Working with partners and choosing their own challenge? They are going to LOVE it! Thanks for sharing your great ideas with us!

Thanks so much for sharing. I can think of several ways that I can use it.

I am building an animated slide show that adds the magnifying glass every few minutes similar to your other cool automated presentations! You have inspired me to automate everything!
