What Is Benchmark MA.1.GR.1.1?
Children identify, compare, and sort flat (two-dimensional) shapes and solid (three-dimensional) shapes by their defining attributes, like the number of sides, vertices (corners), faces, and edges, and whether sides are straight or curved.
Flat shapes: circles, semi-circles, triangles, rectangles, squares, trapezoids, and hexagons. Solid shapes: spheres, cubes, rectangular prisms, cones, and cylinders. Flat and solid shapes are sorted separately.
Official benchmarkIdentify, compare and sort two- and three-dimensional figures based on their defining attributes. Figures are limited to circles, semi-circles, triangles, rectangles, squares, trapezoids, hexagons, spheres, cubes, rectangular prisms, cones and cylinders.
How it is tested: Grade 1 students take FAST Star Math, Florida's math test for Kindergarten through Grade 2.

Name the Solid Shape
Which solid shape has 6 square faces?
- 1A cube has 6 faces, and they are all squares.
Answer: A cube
Common Mistakes to Watch For
Naming a shape by how it is turned
Wrong:A square turned on its corner is a different shape.
Turning a shape doesn't change it. It still has 4 equal sides and 4 square corners, so it is still a square.
Using a flat shape name for a solid shape
Wrong:A ball is a circle.
A ball is a solid shape: a sphere. A circle is flat.
Helpful Math Tip
Go on a shape hunt around the house and sort what you find into groups. Ask your child to explain the rule for each group.
