Unit check: before and after
Two short paper checks made from this unit's own worksheets. Give Check A before you teach the unit and Check B after it, and you can see what changed. Each part belongs to one lesson.
- Part 1: Lesson 1, Number bonds to 5 and to 10 (1 task)
- Part 2: Lesson 3, Take apart 8 and 9 (1 task)
- Part 3: Lesson 4, How many more to make 10? (1 task)
- Part 4: Lesson 5, Partners of 10 (1 task)
- Part 5: Lesson 6, Add and subtract to color (1 task)
- Part 6: Lesson 8, Odd or even? (1 task)
Not in the check: Lesson 2, Lesson 7. Worksheets that cannot be split into single tasks are left out.
Printing a check counts as a download, like any worksheet.
The answer keys and the teacher pages come with the paid Teacher plan.
This is a classroom check of this unit's lessons. It is not a standardized test, and its points are not a grade.
