Applied Problem Solving
📋 What it is
Use measurement in multi-step real problems — mixing units, converting, and calculating.
🗣️ Coach says
Applied problems combine skills: convert units, then calculate, then answer. "How many 250 mL cups from a 2 L bottle?" needs a conversion (2 L = 2000 mL) then a division. Read carefully, convert, compute.
🧠 Memory hook
Convert to the SAME unit first, THEN calculate. Mixed units are the classic trap.
😂 Giggle
Area and perimeter walked into a room.
Area said, "I've got you covered." Perimeter said, "I've got you surrounded."
😲 Whoa!
Recipe scaling is applied measurement: doubling a cake means converting and multiplying every ingredient at once.
✅ Quick check: How many 250 mL cups fill from a 2 L bottle?
Say your answer out loud first — then reveal.
8 — convert 2 L to 2000 mL, then 2000 ÷ 250 = 8.
You must convert to the same unit before dividing.
🧪 Try it! (2 minutes)
Work out how many 200 mL glasses you can pour from a 1 L carton (convert, then divide).
