Recognize a Solid from Its Parts

Supplied materials

• Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
• Supplied worked-case record: A solid with two matching circular bases joined by a curved surface is a cylinder.
• All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

A cube has six square faces. A cone has one circular base and a pointed end. A cylinder has two circular bases and a curved surface. A sphere is round all around with no flat face. These parts help distinguish solids that look similar in a drawing.

Match the supplied parts to a solid name. Draw a simple labeled model or explain the parts aloud. Check that all stated parts fit, not just one familiar feature.

Count the flat bases or faces stated in the description. One circular view does not tell you whether a solid is a cone, cylinder, or sphere. Draw a side view and label the bases or tip named in the prompt.

1. Draw a side view and label the bases or tip named in the prompt.
2. Follow the worked example. Point to each number or shape feature and say what it tells you.
3. Match the supplied parts to a solid name.
4. Try the question and then the three practice questions. Check your answers and explain any change you make.
