# Addition and Subtraction of Integers

Strand: Number
Outcome: 6

## Step 3: Plan for Instruction

### Guiding Questions

• What learning opportunities and experiences should I provide to promote learning of the outcomes and permit students to demonstrate their learning?
• What teaching strategies and resources should I use?
• How will I meet the diverse learning needs of my students?

### A. Assessing Prior Knowledge and Skills

Before introducing new material, consider ways to assess and build on students' knowledge and skills related to counting.

### B. Choosing Instructional Strategies

Consider the following strategies when planning lessons.

• Access prior knowledge on integers outlined in the achievement indicators for Grade 6.
• Use a problem-solving context that relates to students and applies the addition and subtraction of integers.
• Connect problems applying addition and subtraction of integers to similar problems with whole numbers. Review the types of problems for addition and subtraction, such as part-part-whole, comparison and join or separate.
• Connect the subtraction of integers to the addition of integers.
• Have students explore sums and differences of integers by using a variety of manipulatives, such as integer tiles and arrows on a number line.
• Emphasize that students connect the concrete, pictorial and symbolic representations for sums and differences of integers.
• Have students justify the strategies they use in finding sums and differences of integers and critique strategies used by others.

### C. Choosing Learning Activities

Learning Activities are examples of activities that could be used to develop student understanding of the concepts identified in Step 1.
