I use this short computation screen with 5th & 6th grade students to get a basic sense of their abilities regarding number sense and all four operations using whole numbers and decimals. It can be completed as a pre-screen in one class period. This product includes an answer key. There are 2-6 questions for each skill. The skills included are:
1) place value
3) understanding of inverse operations
4) subtraction with regrouping
5) addition of decimals
6) multiplication of whole numbers and decimals (2x2 and 3x3)
7) long division with whole numbers in decimals.
