This Application Problem is a part of the Lesson 8, Unit 1, Grade 1. Rayden received 9 stickers at school. He received 5 stickers in the morning. How many stickers did he receive in the afternoon? Draw a picture, a number bond, and a number sentence to show how you know. This problem is designed as a bridge from the previous lesson's focus on decompositions of 9 and provides a lead-up to today's Concept Development as students prove that 10 can be decomposed in many ways.
