CCSS.Math.Content.K.G.B
The standard
Analyze, compare, create, and compose shapes.
Common Core State Standards for Mathematics
What this standard means
Students need to look closely at shapes, talk about their parts, compare how they are alike and different, make shapes, and put shapes together to make new ones. They should use words like sides, corners, round, flat, same, different, bigger, and smaller.
Mastery looks like a child sorting shapes by attributes, explaining why a rectangle is not a triangle, building a larger shape from smaller shapes, and copying or making simple designs. Students often get stuck on orientation, thinking a turned square is not a square, or naming shapes by color or size instead of attributes.
Ways to teach it
- Give students pattern blocks and ask them to build a house, then name the shapes they used and count corners and sides.
- Ask, “How are a square and a rectangle the same, and how are they different?” and have students answer with a partner.
- Show three shapes and ask students to point to the one that has no corners, then explain their choice.
- Take a shape walk in the classroom and have students find circles, rectangles, squares, and triangles on real objects.
