Angles and Triangles
Strand: Shape and Space (Measurement)
Outcome: 1
Strand: Shape and Space (3-D Objects and 2-D Shapes)
Outcomes: 4 and 5
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 and Skills 
B. Choosing Instructional Strategies
Consider the following instructional strategies for teaching constructing and comparing triangles, and describing and comparing regular and irregular polygons.
- Connect new geometric concepts to previous concepts learned.
- Connect the geometric concepts to the real world.
- Connect classification of triangles according to angles with classification of angles according to their measure.
- Integrate the specific outcomes; e.g., focus on triangles as examples of polygons and the equilateral triangle as an example of a regular polygon where all angles have the same measure.
- Provide hands-on experiences by having students construct various 2-D shapes and then focus on their properties.
- Use concept attainment with examples and non-examples of a given geometric concept to promote discussion and critical thinking so that students construct their own meaning and write their own definition.
- Have the students sort 2-D shapes into groups and explain the sorting rule.
- Have the students discuss the similarities and differences between two geometric concepts.
- Consolidate learning of the various geometric concepts through different strategies; e.g., Frayer Model, tree diagram and semantic feature chart.
C. Choosing Learning Activities
The following learning activities are examples
that could be used to develop student understanding
of the concepts identified in Step 1.
