Welcome teachers! You can use this resource in a variety of different ways, but I would most likely use it as a SCOOT review around the classroom. The 20 questions can be taped at different locations around the room. Students travel to each location to answer the question and record their answer on the recording sheet. The students can then receive immediate feedback by checking their answers from the answer key. Students could answer these questions for morning work, at centers, or it could be incorporated into a whole-group review.
You may also want to print these cards in color and laminate them for future use. If you are using these review cards at a center, you could have students place the recording sheet behind a clear page protector. Students could then record their answers with a dry-erase marker and check their work when finished.
