What is Sale Price Calculator?
Sale Price Calculator is a math game that teaches students to calculate discount prices — a critical everyday skill. Players see an item with its original price and a 'percent off' tag (like you'd see in a real store), then must determine what the new sale price is. The game covers the four most common discount percentages (10%, 25%, 50%, 75%) and uses a visual discount bar to help students understand that a percentage is a fraction of the whole price.

Frequently Asked Questions
What grade level is this game for?
Designed for grades 3–5. Easy mode (50% only with round prices) works for grade 3. Medium and Hard modes challenge grade 4–5 students with more percentages and non-round prices.
How do I calculate a discount?
Multiply the original price by the discount percentage, then subtract. For 25% off $20: 25% × $20 = $5 savings, so the sale price is $20 - $5 = $15. For 50% off, just divide by 2!
What does the visual bar represent?
The filled portion of the bar represents the sale price (what you pay). The empty portion represents the discount (what you save). This helps students see percentages as parts of a whole.
Why are the wrong answers so close to the right one?
The distractor answers are based on common mistakes: calculating the savings amount instead of the sale price, applying the wrong percentage, or arithmetic errors. This helps students learn to check their work.
What is the streak counter?
The streak counts correct answers in a row. Making a mistake resets it. It encourages careful thinking over quick guessing.
Is 50% off always half?
Yes! 50% off means you pay half the original price. This is the easiest discount to calculate mentally, which is why it's the only one used in Easy mode.
