Similar Solids and Proportional Reasoning
Double the dimensions, quadruple the surface area. Pairs build similar prisms and compare the ratios of their surface areas and volumes to the ratio of the heights. Given two similar cones, partners determine the ratios of the lateral...
Curated OER
Net (Cone)
In this cone worksheet, students cut out, fold and assemble a solid figure of a cone by using the net provided on this page. No written directions are given.
Curated OER
2D and 3D figures
In this 2D and 3D figure worksheet, students name different shapes and decide if they are polygons or not. Students complete 8 problems.
Curated OER
Parallel and Perpendicular Lines
Young geometers get some solid skills practice in evaluating slopes. Beginning with the basics of slope through two points and progressing through properties of parallel and perpendicular lines, the building of skills is gradual and...
Curated OER
Shapes
In this geometry learning exercise, students analyze 9 drawings of geometric shapes and solid figures. Students write the name of each shape. There is no word bank.
Illustrative Mathematics
Box of Clay
What happens to a volume when you scale the dimensions of a rectangular prism? For this problem, a box of clay is increased in each dimension, with the intent to see if learners can generalize the result. The addition of physical models...
