How to Use This Pack

Two pages that go over the whole unit on addition strategies to 20, 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.

In the Classroom

Do the review together the day before the test, with a double ten frame and counters out. Work a question, then let students try the next one on their own, and stop on any that trip up more than a few. Many questions show the strategy as well as the answer, so talk about the work as well as the sum. The keys name each question's lesson, so a question the class misses points to the lesson to go back to.

At Home

Use the review as practice before a test at school. Read each question aloud with your child, and ask them to say how they found each sum.

Tips for Success

Read the questions aloud for students who are still learning to read
Ask students to say the double they used on the near doubles question
Keep a double ten frame on the desk for making a ten
On the three number question, any order works; the key shows the ten or double first
Go back to the lesson the key names for a question the class misses

Common Core Standards Alignment

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

K.OA.A.3 Break a number up to 10 into two parts several ways, recording each as a picture or equation (7 = 3 + 4).
K.OA.A.4 For a number from 1 to 9, find the partner that adds with it to 10, and show it in a picture or number sentence.
1.OA.A.2 Solve story problems where three numbers are added together for a total of 20 or less.
1.OA.B.3 Use the order and grouping rules of addition as shortcuts, for example knowing 5 + 9 gives the same answer as 9 + 5.
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.
