This simple assessment can be used as a formative or summative assessment. I have given it as a pre and post formative assessment for a unit I taught about place value and comparing, adding, and subtracting decimals. You could give all of it or cut it apart to only test one standard at a time.
This assessment covers Common Core Standards 5.NBT.A.3.A, 5.NBT.A.3.B, 5.NBT.A.4, 5.NBT.B.7, and 5. NBT.A.1.
This resource includes an answer key at the end.
