    Math Unit 4 Test: Measurement & Data

    Directions for the grown-up

    Give this test on a calm day, after the unit's last lesson. Sit with your child and read the directions for each part aloud. Read any item aloud if your child asks. Reading is not what this test checks. Do not time the test. The time given is only a guide, so you can plan. Take a short break between parts if your child is tired. Do not teach or hint during the test. If your child is stuck, say "Do your best, then we can move on." When you score, use the answer and the partial-credit notes for each part. Then add the points and find the level at the end. Your child may use the tools from the lessons: a ruler, the paper clock and the coin jar (real coins and play bills). The clock items describe the hands in words; your child may set the paper clock to match.
