This Application Problem is a part of the Lesson 9, Unit 1, Grade K. When giving directions for the Application Problem, show a picture of a caterpillar to assist your English language learners and special needs students in understanding your directions. Draw a caterpillar pet that has 4 different parts. Show your pet to a friend. This is a classic sequence of concrete to pictorial. They made a caterpillar yesterday with cotton balls, and today they draw one.
