How to Use This Pack

The unit test on subtraction to 20 and the equal sign. 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. The pre-check and the unit review are packs of their own.

In the Classroom

Give Form A the day after the unit review. Question 8 (the balance) and question 9 (true or false) check the meaning of the equal sign; have counters or a pan balance ready for students who want to build it. The answer keys name each question's skill, so a missed question points to the lesson to reteach.

At Home

Use Form B as a check after the unit. Read each question aloud with your child, and ask them to explain how they found each answer: did they count back, think addition or get to 10 first?

Tips for Success

Read the questions aloud for students who are still learning to read
Counting back works best for taking away 1, 2, 3 or 4
To subtract 9 or 8, think addition: 8 and what make 15?
The equal sign means both sides are the same, not "the answer comes next"
Use Form B as a retake after reteaching what was missed

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

K.OA.A.1 Show adding and taking away in many ways: fingers, objects, pictures, sounds, acting out, words, or number sentences.
1.OA.B.4 Treat subtraction as finding a missing addend: to solve 12 - 9, ask what added to 9 makes 12.
1.OA.C.5 Connect counting with adding and subtracting, such as adding 4 by counting on four more.
1.OA.C.6 Add and subtract to 20, working fluently within 10, with strategies like counting on, making ten, fact families and doubles plus one.
1.OA.D.7 Know the equal sign means both sides have the same value, and decide whether addition and subtraction equations hold true.
1.OA.D.8 Solve for the missing number in adding or subtracting equations like 9 + ? = 15 or ? - 4 = 6.
