Here's a set of over 100 terms for student review. Either have students record their understanding of the word's meaning on the back of the card, flash the cards and see which terms students know, give one page to each student to define, etc.
Whichever method you choose, there are enough easy and a few challenging terms for everyone. A blank sheet has been included for your own set of terms.
The intention is to provide a quick review to build each child's sense of confidence before testing, and to reassure, "You will do just fine!"
