10. Number Sense: Integers

By the end of this unit I will be able to:

• compare and order integers

• add integers

• subtract integers

I have only have one video on this which explains both adding and subtracting integers. Students will have access to manipulatives (chips/counters) if they would like to use them.

I strongly suggest that all students watch this video:

Students should be able to explain:

• Integer Ninja Battle (adding integers)

• how the Integer Dance works

The following link contains both reach ahead and remedial work on integers. The reach ahead work has to do with multiplying and dividing as well as order of operations (all of which will be covered in Grade 8).
