This download includes a practice problem booklet that you can print for each student to complete. There is a section on subtraction, addition, multiplication, division, time, money, perimeter and area, and story problems. This download also includes an answer key. This math mixup allows teachers to assess what areas students need the most help with. It is a great tool to use in the beginning of the year, middle of the year, or end of the year to see what areas you should recover. The problems in each section vary in difficulty. They include easier and harder questions under each subject matter. You could start this with third grade and use some of the harder concepts as challenge work. It would also work great for fourth or fifth graders too.
