Directions Part 1 1.Look in the glossary for the definition of each vocabulary word. 2.Find the matching definiton in your Ch. 2 Vocabulary packet. 3.Write the vocabulary word that matches the definition on the back of each box. Part 2 1.Cut out the definitions and vocabulary words. 2.Pair the definition with the vocabulary word. 3.In your interactive notebook, glue in each vocabulary word and it’s definition side by side.
