Here's a quick and fun way for your first graders and second graders to practice combinations of numbers that make sums of twenty. There's lots of mental math here, since they'll be hunting for combinations of two, three, and four addends, and quite often finding a combination of ten along the way.
For a little accountability piece (and because, let's face it, we all know that nobody can stand correcting a paper like this with all those crazy circles your kiddos will make!), on the back of the paper they'll be writing five of the combinations they find. Click to download this fun freebie!
After your kiddos fall in love with these, you might want MORE! Here's a complete set of sum searches to build strong fact knowledge for totals of five through twenty. Each search comes in two formats, one for individual practice and one for a partner game. Click to see it now!
Happy Teaching!
