How to Use This Pack

The unit test for the first unit of 2nd grade, facts and strategies within 20. 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. Questions 5 and 6 are eight facts each: give the point when all eight are right, or score them by the fact if you like, and time them if you are checking fluency. Questions 8 to 12 (three numbers, fact families, missing numbers, = and ≠) are taught in 2nd grade in some states: leave out the ones your class does not learn and score out of what is left. 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. Ask your child to say how they found each answer: a double, a ten, or an addition fact they know.

Tips for Success

Ask students to show the ten they made, not only the answer
Go over the unit review the day before the test
On the near doubles, ask "1 more or 1 less than the double?"
Read ≠ aloud as "is not equal to"
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:

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.
2.OA.B.2 Add and subtract to 20 quickly using strategies done in the head, and by year's end instantly recall every sum of two single-digit numbers.
2.NBT.B.6 Find the sum of two, three or four two-digit numbers using place value and properties of addition.
