Use a Picture Graph Key Greater Than One

Supplied materials

• Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
• Supplied worked-case record: The key says one square stands for four votes.
• All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

A picture graph key may assign several items to each symbol. Count the symbols and multiply by the key to find the actual count. Comparisons can use either converted counts or a symbol difference multiplied by the same key. Always name the recorded quantity.

Read the supplied symbol value. Multiply the category’s symbol count by that value. Check by repeated addition of the key amount and explain why symbol count alone is not the item count.

Write the key next to the row before multiplying. Symbols and recorded items are different units when the key exceeds one. Replace each symbol mentally with a group containing its key amount.

1. Replace each symbol mentally with a group containing its key amount.
2. Follow the worked example. Point to each number or shape feature and say what it tells you.
3. Read the supplied symbol value.
4. Try the question and then the three practice questions. Check your answers and explain any change you make.
