The 50 word Challenge is appropriate for 4th and 5th graders. I chose words from various sources. Words included in this challenge are Common Core Academic Vocabulary. Words chosen are Tier 2 Words. I chose words that students would encounter in their studies as well as in their testing. Students are rewarded when they complete the challenge. The rules are in the front of their notebook. I have included covers for 50, 40 and 25 word challenges. A list of words is included for reference.
