Teaching Table
Set out your lesson
Count boundary sides and test a vertical mirror line in the displayed orientation.
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.
Use a paper fold if printed or imagine folding left to right on screen. Do not label symmetry inside the learner graphic. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Identify and describe properties of 2-D shapes including the number of sides and line symmetry in a vertical line
Specified polygons and page orientation only; description of all 2-D shapes is not claimed.
- partial: Count the number of sides of a given 2-D shape
Specified polygons and page orientation only; description of all 2-D shapes is not claimed.
- partial: Identify whether a 2-D shape has a vertical line of symmetry
Specified polygons and page orientation only; description of all 2-D shapes is not claimed.
- partial: Use properties (number of sides, symmetry) to describe and distinguish between shapes
Specified polygons and page orientation only; description of all 2-D shapes is not claimed.
- partial: Can {{name}} count the sides of a shape and say whether it has a line of symmetry — for example, knowing that a rectangle is symmetrical but a scalene triangle is not?
