Unit 2, Lesson 2# Ten-Frame Flashcards Routine

Massachusetts Department of Elementary and Secondary Education 60 min(s)

The focus of this unit is for students to gain an understanding that the numbers 11-19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones. They will know that ten ones are equal to one ten. Ten frame cards use the anchors of 5 and 10. They help in moving the student away from counting by ones to seeing small groups of numbers (subitizing).
