Find 10 more, 10 less, 100 more and 100 less, and add and subtract hundreds and tens
Add with base-ten blocks and trade, add by partial sums, and add in columns
Subtract with blocks by breaking a ten or a hundred, and break apart the number taken away
Subtract in columns (across a zero too)
Find who is right and show how they know
The last two questions (solving a story problem within 1,000 and writing a story for a number sentence) are for the states that teach them in 2nd grade
Answer keys name the lesson and skill of every question

How to Use This Pack

The unit test for the unit on adding and subtracting within 1,000. 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 6 and 8 are three column problems each: give the point when all three are right, or score them by the problem if you like. Questions 11 and 12 (solving a story problem and writing a story for a number sentence) are taught in 2nd grade in some states: leave them out if your class does not learn them and score out of 10. The answer keys name each question's skill, write every carried 1 and traded digit, and cross out the blocks, 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 what they did in each place: did the ones make a new ten, or did they need to trade a ten for 10 ones?

Tips for Success

Go over the unit review the day before the test
Ask "do the ones make a new ten?" before every column problem
Have students check a subtraction by adding the answer back
On Who is right, ask what mistake the other animal made
Use Form B as a retake after reteaching what was missed
