These 80 and 100 problem addition worksheets are designed to incrementally build addition fact competency. Use these as two minute timed addition tests, which are great at-home practice even if your school is only doing one minute tests.
Similar to the worksheets in the previous section, these addition worksheets gradually introduce a small number of addition facts. Students should practice each level until they have mastered the new facts before moving on. These 100 problem worksheets are designed to be slightly more challenging and should be something that can be completed in two minutes or less by students. I typically use the final sets of addition worksheets in this section for addition facts review or for assessment testing.
