The leaderboard shows one player hit 150% of the goal and a bonus round gives a 0.5% boost. How can a percent be more than the whole, and how can one be a tiny sliver?

Arcade Builder Challenge
The arcade just posted its monthly leaderboard! Some players crushed the target score — one player hit 150% of the goal! Meanwhile, a rare bonus round gives only a 0.5% point boost. You need to understand what these unusual percents really mean to read the leaderboard correctly.
Concept Launch
💡 How can a percent be more than the whole, or smaller than a tiny piece?
100% means one whole. A percent greater than 100% is more than the whole. A percent less than 1% is a very tiny part.
To change any percent to a decimal, divide by 100 (move the decimal point two places to the left).

The leaderboard shows one player hit 150% of the goal and a bonus round gives a 0.5% boost. How can a percent be more than the whole, and how can one be a tiny sliver?
👂 Listen For
Students explain 150% is more than one whole (the player beat the goal) and 0.5% is far less than one whole (a tiny boost), connecting to the idea of 100% as the whole.
Extend: 100% means the whole goal. Explain why scoring 150% does NOT mean the player made an error, but scoring '150% correct on a test' usually would.

When you wrote percents like 150% and 0.5% as decimals, what did you notice about their size compared to 1?
👂 Listen For
Students state 150% = 1.5 (greater than 1) and 0.5% = 0.005 (much less than 0.01), and recognize these forms are equivalent.
Extend: Why does 0.5% turn into 0.005 and not 0.05? Explain the role of dividing by 100, and write 150% as a mixed number too.

Real-World Connection
🌍 Math in the Wild
A different arcade machine pays a jackpot of 300% of your tokens if you win. You inserted 30 tokens. One friend says the jackpot is 90 tokens. Another friend says it's 33 tokens.
✍️ Connection Reasoning
Who is correct, and how many tokens does the jackpot pay?
The friend who said ___ tokens is correct because 300% of 30 = ___ × 30 = ___. The other friend treated 300% as if it were ___% instead.
Turn & Talk — Connect
A jackpot pays 250% of your tokens and you inserted 40 tokens. One friend says 100 tokens, another says 60. Who is right, and why does '250%' mean more than your tokens?
👂 Listen For
Students convert 250% to 2.5, multiply 2.5 x 40 = 100, and explain that over 100% means more than the original 40 tokens.
Extend: The friend who said 60 found 150% of 40. Explain the mistake they likely made, and describe a jackpot percent that WOULD give exactly 40 tokens.

🎯 Listen For · Common Errors
• Students explain 150% is more than one whole (the player beat the goal) and 0.5% is far less than one whole (a tiny boost), connecting to the idea of 100% as the whole.
• Students state 150% = 1.5 (greater than 1) and 0.5% = 0.005 (much less than 0.01), and recognize these forms are equivalent.
• Students convert 250% to 2.5, multiply 2.5 x 40 = 100, and explain that over 100% means more than the original 40 tokens.
• Listen for students naming a specific strategy tied to 6.RP.3c — not just "I multiplied." They should connect steps to the key idea.
Common mistake: A common mistake in Percents Greater Than 100% and Less Than 1% is skipping the key idea: "To change any percent to a decimal, divide by 100 (move the decimal point two places to the left)." — always check your work against this rule before you submit.
Answer Key (Teacher Appendix)
Hide this slide during presentation or move to the end of your copy.
✓ Practice 1: 0.004 — 0.4% = 0.4 ÷ 100 = 0.004. Move the decimal point two places to the left.
✓ Practice 2: 1.25 — 1.25 = 125%, which is greater than 100%. The other values are all less than 1 (less than 100%).
✓ Practice 3: 2.0 — 200% ÷ 100 = 2.0. Percents greater than 100% become decimals greater than 1.
✓ Practice 4: 0.005 — 0.5% ÷ 100 = 0.005. Move the decimal two places to the left.
✓ Exit ticket: It equals 0.0025 as a decimal — 0.25% = 0.25 ÷ 100 = 0.0025. It is much less than 1%, not equal to 1/4.
