Compare Height from One Ground Line

Supplied materials

• Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
• Supplied worked-case record: Tower A is 3 equal blocks high and tower B is 6 blocks high.
• All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

Height describes how far something reaches upward from its base. Put both bases on one ground line before comparing. A drawing placed higher on the page is not necessarily taller. Only the distance from its own base to top measures height.

Draw the stated towers on one horizontal ground line using equal blocks. Count or compare how far their tops rise. Name the taller tower without moving its base upward.

Use one ground line for both towers. A higher position on the page is not the same as a taller object. Draw one base line and build both block towers upward from it.

1. Draw one base line and build both block towers upward from it.
2. Follow the worked example. Point to each number or shape feature and say what it tells you.
3. Draw the stated towers on one horizontal ground line using equal blocks.
4. Try the question and then the three practice questions. Check your answers and explain any change you make.
