McGraw Hill Wonders Grade 4 Unit 1 Week 1 vocabulary inventory - This graphic organizer is a great formative assessment when introducing new vocabulary for the lesson. Students have the opportunity to practice using context clues to determine the meaning of new vocabulary. Sentences are provided and students are given space to write a brief definition of what they believe a word means. After class discussion students are provided with a space to write the actual meaning of the word. This can be used in whole group or small group and provides students an opportunity to write and explore.
