Looking at objects

Common sticking points

• The big one is counting only the cubes you can see. A drawing shows the outside, and cubes hide behind, below and underneath other cubes — so what is visible is never a promise about what is there.
• Another is drawing a tower of three as three squares in a row on the top view. Height does not spread sideways: from above, a stack of three covers exactly the same square as a single cube. That is why a plan writes the height inside the square.
• A third is treating one matching drawing as proof that two objects are the same. Objects that agree from the front can disagree completely from the side — one view is a clue, not a proof.

Try this together

Build something small out of anything stackable — cereal boxes, books, LEGO. Take turns drawing it from the front, from one side, and from directly above, without saying which is which. Then swap drawings and try to rebuild each other's object. The argument about whose drawing was not enough IS the lesson.

1–5 minutes, no materials to buy, nothing to hand in.
