Product Description
Students read about the additive inverse - the property of numbers that allows us to convert subtraction to addition.

In this activity, students read about the additive inverse and identity to better understand how subtraction works.

Students are presented with the subtraction algorithm where they are given examples of applying it to addition and subtraction expressions. Students are presented with the zero pairs counter model that allows them to manipulate addition and subtraction of integer values.

Throughout the reading students are presented with questions that force them to reflected upon what they have read.

At the end students are presented with several expressions to which they are apply the algorithm following the steps the read about.

This will take longer or shorter depending on the reading level of the students. Younger students will most likely need the reading process modeled in the classroom while older students may be assigned the reading as homework.
