二维图形（6岁以上）
Description
Identify and describe properties of 2-D shapes including the number of sides and line symmetry in a vertical line
Mastery Evidence
- Count the number of sides of a given 2-D shape
- Identify whether a 2-D shape has a vertical line of symmetry
- Use properties (number of sides, symmetry) to describe and distinguish between shapes
Assessment Prompt
Can your child 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?
