This packet begins with ideas for how to reinforce and enrich learning related to addition and subtraction, including games. The worksheet provides spaces for students to write 4 word problems and then solve them using the standard algorithm. These problems should include addition and subtraction with up to 3-digits. You can decide if you want to incorporate regrouping or not. This can be accomplished in partners where one partner writes the problem and the other solves it. If students can write their own word problems, they will have an easier time solving them.
