A few weeks ago, I saw a picture on Pinterest of a hundred chart that had been cut up and turned into a puzzle. I loved it!
I got to thinking, wouldn't it be great to put a twist on that and turn it into a math center? Here's what I came up with . . .
I started with a few hundred charts copied onto different colors of tagboard. I like to enlarge my charts to 11 x 17 to make them easier to work with. Just like in the pin I had seen, I cut the charts into puzzles.
Then, I simply removed some numbers from each puzzle.
Now, it's set up so kids can put the puzzle together and then figure out (and record) which numbers are missing. I have kids list the missing numbers for each color. Voila - a bit of accountability.
I was lucky ~ I happened to have envelopes the same color as my puzzles. But, if I didn't, I'd just use ziploc bags and color-code them with a sticker or dot.
To differentiate, I'm thinking of letting kids who need extra support build directly on another hundred chart.
After kids are confident with this, we'll move on to puzzles using a 120 chart!
For a challenge, kids could have to explain in writing how they know which numbers are missing. (Another challenge I am considering is having kids find puzzle pieces with one or more lines of symmetry.)
Hope you enjoy this idea. Let me know if you think of more twists to add. Thanks for stopping by and taking a look! :) Anne
