This activity is for 4th-6th graders and it involves decimal addition and subtraction. In this activity, you can use the materials provided or you can add to it. In my personal classroom, I had students create trifold menus out of copy paper and let them get creative with it. Then they were assessed using this activity here. If you do the custom menus, this activity could take 2-3 days, if you just use this sheet it could take 1-2 days to complete.
