Students count by tens to solve a problem using an open number line. By the end of the lesson or a series of similar lessons students will use a number line to solve story problems. Three strategies for solving the story problem are shown on the blackline. After each strategy ask students to share their observations. Have students solve 2-3 problems independently using an open number line. After reading the first problem ask students to retell the story.
