Students identify correct simple machine names and basic facts. Part A asks them to fix three sentences that misname machines — including a seesaw called a pulley and a ramp called a wedge. Part B has four fill-in-the-blank problems about how simple machines change work, the number of types, and the fulcrum. Part C presents three true-or-false statements about levers, inclined planes, and screws.

Correcting misidentifications at the easy level builds accurate vocabulary before students encounter all six machines.
