Give groups a 2 or 3 digit number less than 800. Have one student model the number with place-value block. The student to the right says the name aloud while pointing to the blocks. The next student writes the expanded and standard form of the number. Have the last student write the word name of the number and say it aloud.
Groups can repeat the exercise, starting with a different student each time.
Display a list of 20 word names for students to reference. Call out numbers to children and have them write the number on a place-value chart.
