This is a one page worksheet on basic math facts. It has every possible addition problem using numbers between 1 and 9. A great fill in or sponge. You can even give a star or prize for getting 100%. Probably geared more for first grade, perhaps late kindergarten. Perhaps a good first day or so worksheet for second grade just to test. You could do time trials to make it harder. Make copies for homework practice. Be sure and check out more teacher resources at Teachersindex.com
