Finding Discount Amounts for 3rd Grade
By Majlinda T.
A practice worksheet that walks 3rd graders through calculating the discount amount on sale items, using a three-step method (identify the price, identify the percent off, then multiply) with worked examples and a tape diagram. It builds percent-of-a-number reasoning and step-by-step problem solving, and works well as a guided practice set in a 30-45 minute math block.

Teacher Guide & Tips
- Introduce the key terms (original price, discount percentage, discount amount) on the board first, then model the $20 shirt example aloud before students work independently.
- Discussion question: Why does a 10% discount on a $20 item save less money than a 10% discount on a $200 item?
- Scaffold for struggling readers: Provide a visual of the three steps posted at the table and let students use the tape diagram to see the price split into parts before multiplying.
- Extension for advanced students: Ask them to find the sale price (original price minus the discount amount) and compare two sales of equal percentages on different items.
- Estimated time: About 30-40 minutes for the full set, including the modeled example and a short review of answers.
