Teacher's field guide

What Students Need to Do: Students name the parts of a familiar object and tell what each part does. They predict what will change when a part is taken away.
What Mastery Looks Like: A student can point to a toy car’s wheels and explain that it may wobble if one wheel is gone. They can make a similar prediction about another object.
Common Misconceptions: Some students think any missing piece will stop an object from working, even if that piece is only decoration. Others can name the missing part but not explain what it did.
How to Assess It: Show a picture of a wagon with one wheel missing. Ask, “What might happen when you push it? Why?”

Lesson moves

Build a block bridge with two supports, remove one, and have students test whether a toy animal can cross.
Show a backpack without straps and ask, “How could you carry it now? What did the straps help you do?”
Play a matching game with pictures of objects missing a part and cards showing what those parts do.
Let students make a pencil mark, then try to erase it with a pencil that has an eraser and one that does not.
