Using Strip Models to Explain Percent

Step-by-Step Guide Using Strip Models to Explain Percent

1. Understand the problem: Read the problem carefully and identify the information provided and the information that needs to be found.
2. Draw a strip model: Draw a strip divided into equal parts, with each part representing a certain percentage. The strip can be divided into 100 equal parts, with each part representing 1%.
3. Identify the whole: Identify the total amount or quantity that the percent represents.
4. Shade in the appropriate number of parts: Shade in the number of parts that represent the percent. For example, if the problem states that an item is 20% off, shade in 20 parts of the strip.
5. Label the shaded parts: Label the shaded parts with the percent or fraction that they represent.
6. Use the strip model to find the part or whole: Use the strip model to find the part or whole by counting the number of shaded parts or the number of unshaded parts and multiplying by the whole.
7. Write the final answer in a complete sentence: Use the information from the strip model to express the final answer.

1. We are given that the shirt is on sale for 30% off and the original price is $60.
2. Draw a strip divided into 100 equal parts.
3. Identify the whole: The original price is $60.
4. Shade in 30 parts of the strip
5. Label the shaded parts: 30%
6. Use the strip model to find the part or whole: 30% of $60 is $18
