The unit test on adding and subtracting decimals. Pages 1 and 2 are Form A. Pages 3 and 4 are Form B: the same questions in the same order with different numbers, for a retake, a make-up or a second seating. Each form has 12 questions, one point each, and a Score line on its first page. Every question is part of the Common Core unit, in lesson order: hundred grids, lining up the decimal points, estimating, money and story problems. The pre-check and the unit review are packs of their own.
Give Form A the day after the unit review. Several questions have two or more parts: give the point when every part is right, or score them by the part if you like. The story problems have a box for the work; the key shows one way to solve each. The answer keys name each question's skill, so a missed question points to the lesson to reteach. No question asks a problem from the unit's exit tickets or from the practice sheets.
Use Form B as a check after the unit. Ask your child to estimate a total at the store by rounding each price to the nearest dollar, then to find the exact total and the change.
