## 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.

Ways to Assess and Build on Prior Knowledge

### 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.
