This Fluency Activity is a part of the Lesson 5, Unit 4, Grade 2. This fluency reviews place value relationships that lead into Lesson 6. Write 10 ones = ten. Draw 10 ones place value disks on the board in ten-frame format and circle them when the students say 10 ones = 1 ten. I'm going to give you a number in ones form. Pull out as many tens as you can, and tell me how many tens and ones there are.
