Addition and Subtraction of Integers

Strand: Number
Outcome: 6

Step 5: Follow-up on Assessment

Guiding Questions

• What conclusions can be made from assessment information?
• How effective have instructional approaches been?
• What are the next steps in instruction?

A. Addressing Gaps in Learning

• Use manipulatives of various kinds to develop and demonstrate understanding of adding and subtracting integers.
• Emphasize the connection between adding integers and subtracting integers.
• Relate adding and subtracting integers to adding and subtracting whole numbers. The types of problems involving the addition or subtraction of whole numbers are the same for fraction problems; e.g., part-part-whole, comparison and join or separate problems. Substituting whole numbers for integers helps students to decide which operation to use in solving the problems.
• Use problem contexts that students can relate to and keep the integers simple initially; i.e., use integers close to zero so that they can easily be represented by using integer tiles or a number line.
• Connect the concrete, pictorial and symbolic modes.
• Provide the option for students to use manipulatives as long as needed, even on tests.
• Encourage students to explain their thinking orally if they have difficulty explaining it in writing.

B. Reinforcing and Extending Learning

Students who have achieved or exceeded the outcomes will benefit from ongoing opportunities to apply and extend their learning. These activities should support students in developing a deeper understanding of the concept and should not progress to the outcomes in subsequent grades.
