#### Introduction

(5 minutes)
• Tell students the story problem, "Kristi had eight pennies. Kristi's friend gave her some more pennies. Now Kristi has 12 pennies! How many pennies did her friend give her?"
• Seat the students in a circle on the rug, or show them pennies on a document camera. Ask students how much a penny is worth. (One cent!)
• Think aloud as you model the problem. Say, "I know that Kristi had eight pennies." Chorally count one penny at a time to show eight. "I want to know how many pennies Kristi's friend gave her. I know she ended with twelve."
• Count on as you create a second pile of pennies, "Nine, ten, eleven, twelve. How many pennies are in this part? How many more did I need to make twelve total?" (Four.)
• Reflect, "That's right! Kristi's friend gave her four pennies!"
