Ask for volunteers to show the jumps they made for a few of the problems on their sheet. Have the class come together in your meeting spot. Allow students time to work together on the number-line hops. Then pass out an Open Number Line Activity Sheet ( M-1-2-2_Open Number Line Activity Sheet.docx) to each pair. Ask students “How can you add 8 using two hops?” Repeat this process until students have a good understanding. Pose another problem, this time starting with the number 46. Students might say they would add 5 to get to 40, and then add 1 more. This time ask students “How can you add 6 to 35 using two hops?” Have students talk with their partner about strategies for solving the problem.Īsk for volunteers. Next plot the 35 on the number line again. ![]() Repeat this process with other off-decade numbers and ask students how to hop to the next decade. Ask students “How can I hop to 50 in just one hop?” Have students share their ideas with a partner. Then record the number sentence 35 + 5 = 40. Draw the hop on the number line and label it with “+5” above the jump. Ask students “How can I hop to 40 in just one hop?”Īsk for ideas. Continue this process until students seem to understand how the number line works. Explain to students that the goal is to hop to the nearest 10. Write a 32 on the number line then count by ones and plot where 40 would be. Show students how an open number line is helpful because you can use it for any numbers or ranges.
