This is a Math Skills Worksheet that provides practice in the operation of addition and also practice in comparing sums. Doing the problems will give students practice in adding and in comparing whether number sentences are equal or not. For each of the 12 problems students supply an equal sign or not equal sign in the blank circles. Since the worksheet is a word document, you can easily change the directions to have greater than and less than signs. There are 12 problems in all, and the worksheet is probably best for 2rd and 3rd graders, but would also be helpful to 4th graders who need review and practice. 1st graders might be able to do the worksheet at the end of the year when they are very proficient in adding. The page could easily be used as an assessment quiz or for homework. For your convenience, the answer key is on the third page of this product.
