How these addition worksheets build math confidence

It begins with counting pictures and sums up to 5. From there your child makes 10 using ten frames, learns doubles, hops along a number line, reaches totals of 20 and tries two-digit sums that need no regrouping. Some subtraction, mixed review, two one-minute drills and six story problems help each fact stay put.

All 358 answers appear across three answer key pages, so checking is quick and you can spot straight away which skill could use another round. Print any page again as many times as you like.
