The unit test 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 11 questions, one point each, and a Score line on its first page. Questions 10 and 11 (four-digit numbers, and = or ≠) are for the states that teach them in 3rd grade. The pre-check and the unit review are packs of their own.
Give Form A the day after the unit review. Questions 2, 5 and 6 are three column problems each, and question 7 is three lines: give the point when all three are right, or score them by the problem if you like. Questions 10 and 11 are taught in 3rd grade in some states: leave them out if your class does not learn them and score out of 9. The keys show one way for the count-up and one number sentence for each story; any jumps that add up to the answer, and any sentence that fits the story, are right (268 + 345 = 613 as well as 613 − 268 = 345). The answer keys name each question's skill, write every carried 1 and traded digit, and draw the jumps of the count-up, so a missed question points to the lesson to reteach.
Use Form B as a check after the unit. Ask your child to estimate first, then check that the answer is close to the estimate.

The unit test for adding and subtracting within 1,000, in two forms. Students add by partial sums and in columns, subtract by breaking apart, counting up and trading across zeros, use a hundred to do mental math, and solve one- and two-step story problems.
