One of the Core Standards and most useful tools in math operations is the skill of recognizing and using different ways to make a number. Test questions like: "Which is another way of making the number 5? 2+2, 1+4, 4+0, or 3+1 ? can be found at each early grade level. This product provides a way for students to manipulate clothespins on colorful number cards so that they can discover for themselves exactly how many correct ways there are to make any one specific number, and then record those ways. The materials are simple, and can be easily made by a parent volunteer, or teacher's aide. The lesson is presented in such detail that it can easily be used for an evaluation lesson, or taught by a newer teacher. Once the materials are on hand, the same lesson can be used again (students swap cards) and then saved for next year. The lesson also explains and illustrates turn-around facts (the commutative property) as a tool in ways to make a number. This product is both effective, fun to students, and easy to use.
