#### Objectives

Students will be able to solve basic addition problems to 20 by composing a 10.

##### Language

Students will be able to explain steps to calculate sums within 20 using counters in ten frames as a visual reference.

#### Introduction

(5 minutes)
• Play "Flash" to help students form mental images of numbers 11-20. Display a blank Double Ten Frame Mat on a document camera, and ask students how many spaces there are (20).
• With the document camera turned off, fill the double ten frames with 14 circular counters.
• Turn on the document camera and let children look at the ten frames for three to five seconds before hiding the counters.
• Ask students how many counters they saw. Accept all answers, and be sure to ask students to explain their thinking.
• Quickly display the double ten frames again, and then hide. Ask students if anyone would like to change their answer.
• Finally, allow students to look closely at the counters and discuss strategies for "seeing" the total. For example, do students count each counter individually, or see a group of ten and count on?
• Continue with a few more rounds focusing on numbers between 10 and 20.
• Tell students that today they will practice composing, or making, a 10 to solve addition problems using ten frames.
