This lesson is aligned to Math Expressions Unit 6 Lesson 10 that focuses on subtracting numbers from zero. It takes the students through the different steps that are needed to subtract the numbers. There are practice problems and then the students complete their workbook page together with the guiding questions on the PowerPoint. Then, the students complete the rest of the problems with a partner. The ending slides can be deleted if you would like to continue working as a whole group.
