Product Description
This assessment includes 6 problems on the first page requiring students to "make a ten". For example, 8 + 4 would be 10 + 2 = 12. There are also 10 addition/subtraction problems (within 20) where students can solve using any strategy they have learned.
The back page of this assessment includes a Doubles/Doubles + 1 chart, and two Fact Family problems.
In addition, the last two problems on this assessment include a NOT multiple choice and an Explanation. For example, which equation is NOT part of this fact family? Explain how you knew this equation was not part of the fact family.
