Shapes are sorted by their sides and angles: a square has four equal sides and four right angles, a trapezoid has one pair of parallel sides, and a triangle can be equilateral, isosceles, scalene or right. On this fifth grade sheet a child looks at nine drawn figures, with small marks for equal sides, parallel sides and right angles, and writes the most exact name for each one.
Every version draws the shapes at different sizes and turned a different way, so the child has to read the marks and not just recognize a picture. The answer key gives the name of every shape.
What your child will learn
Read marks for equal sides and right angles
Name quadrilaterals
Name triangles by their sides
Pick the most exact name
Common Core standard: 5.G.B.4
Worked example
A figure with four equal sides and four right angles is a square, even though it is also a rectangle and a rhombus.
Common mistake
Calling a square a rectangle: it is, but a square is the more exact name when all four sides match.
Helpful hint
Count the equal sides and look for right angles and parallel arrows, then choose the most exact name.
