Two pages that go over the whole unit on adding and subtracting within 100, to do together the day before the test. Its 12 questions are the same kinds as the test's, in the same order, with other numbers, so nothing on the review is on the test. There is no Score line: it is practice, not a grade. The pre-check and the unit test are packs of their own.
Do the review together the day before the test, with base-ten blocks and a hundreds chart on the tables. Work a question, then let students try the next one on their own, and stop on any that trip up more than a few. On questions 7, 8, 9 and 12 students show a strategy; the key draws one way to do it, and any way that works is right. The keys name each question's lesson, so a question the class misses points to the lesson to go back to.
Use the review as practice before a test at school. Ask your child to add 10 to a number in their head, then to explain how they knew.
