Addition and Subtraction Three Digit Card Draw

Sometimes I just make up a game on the spot because it suits what my students need.  That happened last week when my students were finishing up a unit on three digit addition and subtraction.  I knew they had the basic steps, they just needed to practice the process.

So I grabbed a deck of cards and had them grab their individual white boards.  We started coming up with 3 digit numbers, and practiced away!

The game transformed as we played, growing from just addition, to just subtraction.  For a while we played by setting up the problem, then I'd call out "add" or "subtract".  Later, I'd let a child choose.  (They were pretty tricky... they'd figure out which would be easier or which would have less regrouping needed. I was pretty impressed they were figuring that out in their heads!)

The freebie to the right has the directions and a printable work paper for children to work on alone, with a partner, or small group.  The children can work on whiteboards, but the printable is handy to have a record of their  work. Click the image or download HERE to download freebie!
