terrific grade-level CCSS math vocabulary cards are easily accessible online. To prepare for the place value unit, I printed and copied the cards related to our study. Then yesterday, students started the day by completing a crossword puzzle. Later in the day, each child used online tools to make their own crosswords puzzles--puzzles that I'll pass out to the class as one more way to practice the unit vocabulary.
Creating and completing crossword puzzles is a direct, positive way to study and practice unit vocabulary, vocabulary we'll incorporate in our unit exercises and activities in days to come.
