This Application Problem is a part of the Lesson 1, Unit 1, Grade 1. Dora found 5 leaves that blew in through the window. Then, she found 2 more leaves that blew in. Draw a picture and use numbers to show how many leaves Dora found in all. Rather than specifying to write a number sentence or number bond, since it is the first day of school, this Application Problem is more open-ended so that students can demonstrate their thinking and representational skills. This problem serves as a lead-up to the Concept Development of seeing the quantity of 5 and another number.
