This is a 4 day long lesson. This bundle includes an interactive lecture, 3 worksheets,and 2 homework sheets.
This lesson covers subtracting using a number line. The theme for this lesson is railroad train cars - you can always reduce the amount of train cars just like subtracting numbers on a number line. The review sections use material from previous bundles (money and adding/subtracting using pictures)
All the pictures I used in both the worksheets and the lecture notes are real stock footage and therefore appropriate for students at any age.
This is part of a larger lesson bundle that will be coming soon.
