Markup and MarkdownActivities & Teaching Strategies
Active learning works for markup and markdown because students often confuse the base amounts and struggle to visualize how percentages change the value. By manipulating real or simulated prices in hands-on tasks, students directly confront their misconceptions and see immediate feedback on how markup and markdown alter the final price.
Learning Objectives
- 1Calculate the selling price of an item after a given markup percentage is applied to its cost.
- 2Determine the original selling price of an item given its sale price and the markdown percentage.
- 3Compare the final selling price of an item after a markup and subsequent markdown to its original cost.
- 4Explain the difference between the base amount used for calculating markup versus markdown.
- 5Analyze the impact of a 50% markdown on an item's price and explain why it does not return the price to the original cost.

Simulation Game: The Classroom Store
Each group manages a fictional product line, receiving a wholesale cost and a target markup percentage to set retail prices. Groups then face a clearance event and must decide on a markdown percentage that still lets them turn a profit. They calculate their results and present their pricing strategy with full mathematical justification.
Prepare & details
Differentiate between markup and markdown in pricing strategies.
Facilitation Tip: During the Simulation: The Classroom Store, circulate and ask each group to explain aloud which price they are using as the base before they calculate.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Think-Pair-Share: Markup or Markdown , Which Base?
Show four pricing problems, two involving markup (calculated from cost) and two involving markdown (calculated from retail price). Students individually identify the base for each calculation, then pair to compare reasoning. The class discussion focuses on why the choice of base matters and how confusing the two leads to pricing errors.
Prepare & details
Analyze how a store determines the selling price of an item after markup.
Facilitation Tip: During Think-Pair-Share: Markup or Markdown, Which Base?, pause after the pair discussion to have each pair share one key sentence that identifies the base in their scenario.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Error Analysis: The Pricing Mistake
Present a scenario where a store clerk calculated a 30% markup using the retail price as the base instead of the cost. Students find the error, calculate the correct selling price, and determine how much profit was lost due to the mistake. They then write a one-sentence rule to help remember which base to use for markup.
Prepare & details
Evaluate the impact of a markdown on a product's original price.
Facilitation Tip: During Error Analysis: The Pricing Mistake, ask students to rewrite the incorrect calculation on the board using the correct base and percentage.
Setup: Groups at tables with case materials
Materials: Case study packet (3-5 pages), Analysis framework worksheet, Presentation template
Gallery Walk: Price Tags
Post eight product cards around the room, each showing a cost and either a markup percentage or a markdown scenario. Students calculate the final selling price for each and write a sentence interpreting what the percent means in context , for example, confirming whether a sale price still generates a profit above cost.
Prepare & details
Differentiate between markup and markdown in pricing strategies.
Facilitation Tip: During Gallery Walk: Price Tags, require students to leave a sticky note on each poster that states whether the tag shows a markup or markdown and what the base was.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Teaching This Topic
Teachers should emphasize the difference between the two bases from the start by labeling every price with its source: cost, markup selling price, or markdown sale price. Avoid teaching markup and markdown as isolated procedures; instead, connect them to real retail decisions so students see why choosing the correct base matters for profit. Research suggests using visual models like percent bars to separate the base from the added or subtracted portion, which reduces confusion between percent of and percent on top of.
What to Expect
Successful learning looks like students correctly identifying the base for each percentage, applying markup and markdown to the proper starting value, and explaining their reasoning using clear labels and calculations. Students should also recognize when a markdown results in a loss and compare that to the original markup.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Simulation: The Classroom Store, watch for students who treat the 40% markup as a discount from the cost price rather than an addition.
What to Teach Instead
Have students use a percent bar model on their worksheet to shade 100% of the cost and then clearly add 40% on top, labeling each section with its dollar value before they calculate the selling price.
Common MisconceptionDuring Gallery Walk: Price Tags, watch for students who assume a 50% markdown brings the price back to the original cost.
What to Teach Instead
Ask students to calculate the cost from the retail price using the markup percentage shown on the tag, then verify whether the markdown price matches that cost or falls below it.
Common MisconceptionDuring Think-Pair-Share: Markup or Markdown, Which Base?, watch for students who use the same base for both markup and markdown in the same scenario.
What to Teach Instead
Require each pair to write the base explicitly next to their percentage before solving, and have them justify their choice to another pair during the share phase.
Assessment Ideas
After Simulation: The Classroom Store, give students a half-sheet with a new scenario: 'A store buys a hat for $12 and marks it up by 60%. Later, they mark it down by 30%. Calculate the final sale price and profit.' Collect and check for correct bases and calculations.
During Error Analysis: The Pricing Mistake, collect students’ corrected calculations and look for consistent use of the correct base label (cost for markup, retail for markdown) in their work.
During Think-Pair-Share: Markup or Markdown, Which Base?, prompt pairs to share whether a 50% markup followed by a 50% markdown returns the price to cost, and have two pairs present contrasting examples to the class to assess understanding.
Extensions & Scaffolding
- Challenge students to find a real advertisement, calculate the original cost from the markdown price, then determine if the store is still making a profit based on typical retail markups.
- Scaffolding: Provide a template with blanks for each step (cost, markup %, selling price, markdown %, sale price) and sentence starters for explaining the base used.
- Deeper exploration: Have students design a mini-business plan where they set a markup, then experiment with different markdowns to see how profit changes, and present their findings to the class.
Key Vocabulary
| Cost Price | The amount a retailer pays for an item before adding any markup. |
| Selling Price | The price at which a retailer offers an item for sale to customers. |
| Markup | The amount added to the cost price of an item to determine its selling price, usually expressed as a percentage of the cost. |
| Markdown | A reduction in the selling price of an item, usually expressed as a percentage of the original selling price. |
| Profit Margin | The difference between the selling price and the cost price, often expressed as a percentage of the selling price. |
