Visual Prompt

Time Capsule Project

Your team is building time capsule containers to store class memories. Each container is a rectangular prism, and you need to figure out how much each one can hold. That means calculating the volume using whole number dimensions!

👁 I Notice...

🔹 What three measurements do you need to find the volume of a box?

🔹 What does volume tell us about a container?

🔹 How is volume different from the area of one face?

💭 I Wonder...

🔹 If two containers have the same volume, must they have the same shape?

🔹 What happens to the volume if you double just one dimension?

Concept Launch

💡 How do we find the volume of a box?

👩‍🏫 Say: This is the big idea for today. Students should be able to repeat it by the end.

Volume is the amount of space inside a 3D shape. For a rectangular prism (a box), volume = length × width × height, measured in cubic units.

Key Idea:

To find the volume of a box, multiply all three edges: V = length × width × height.

🎯 Listen For · Common Errors

• Students explain volume is three-dimensional, so all three edges (length, width, height) are needed; two measurements only describe one flat face.

• Students connect the folded net to the 3D space inside, and explain volume counts the unit cubes that fill it, computed as l × w × h.

• Students compute large = 7776 in³, medium = 3024 in³, then subtract to get 4752 in³ more, and reason that you must find each volume before comparing.

• Students change in² to in³ and explain that volume fills 3D space (three edges multiplied), while square units describe the flat area of one face.

Common mistake: A common mistake in Volume with Whole Number Edges is skipping the key idea: "To find the volume of a box, multiply all three edges: V = length × width × height." — always check your work against this rule before you submit.

✓ Practice 1: Bin B by 12 in³ — Bin A: 8 × 6 × 5 = 240 in³. Bin B: 9 × 4 × 7 = 252 in³. Bin B holds 12 in³ more.

✓ Practice 2: 84 in³ — V = l × w × h = 7 × 3 × 4 = 84 cubic inches.

✓ Practice 3: 3 cm — V = l × w × h → 120 = 10 × 4 × h → 120 = 40h → h = 3 cm.

✓ Practice 4: Cubic inches (in³) — Volume measures 3D space, so it uses cubic units like in³. Square units (in²) are for area, and inches are for length.

✓ Exit ticket: 220 in³ — V = 11 × 5 × 4 = 220 cubic inches. Remember: volume uses cubic units (in³).
