Questions

What geometry do 1st grade students learn?

In 1st grade, geometry covers defining shape attributes, counting sides and corners, and halves and fourths. Cubles Brain Blocks lets students practice all of it free, one problem at a time, with worked-out steps.

Is this 1st grade geometry practice free?

Yes — every problem is free with no sign-up and no ads, and a new one is generated each time so it never runs out.

Common Core standards covered
  • 1.G.A.1Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
  • 1.G.A.2Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
  • 1.G.A.3Partition 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. Understand that decomposing into more equal shares creates smaller shares.
