3.yes

What students practise

I can describe shapes by their sides and corners and split a shape into equal shares.

Students tell the defining attributes of shapes, put shapes together, and partition circles and rectangles into equal shares named with the words halves, thirds and fourths.

Key words

half: one of two equal shares
third: one of three equal shares
fourth (quarter): one of four equal shares
equal shares: parts that are exactly the same size
side: a straight edge of a flat shape
vertex: the point where two sides meet

Common mistakes

Counts the parts without checking that they are the same size.
Thinks more parts means a bigger share.

Standards

Common Core State Standards this worksheet practises.

1.G.A.1: Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size). (unverified)
1.G.A.2: Compose two-dimensional shapes or three-dimensional shapes to create a composite shape, and compose new shapes from the composite shape. (unverified)
1.G.A.3: Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. (unverified)
