How to use it at home and in class
At home
Go on a shape hunt around the house and name what you find. Ten problems a day works better than a whole sheet at once. Mark them together with the answer key, then ask your child to explain one they got wrong: finding the mistake themselves is where the learning happens.
In class
Use the first row as a warm-up, a full page for independent practice, or five questions as an exit ticket. For a retake or a second group, make a new version with the test maker so every child gets different numbers.
Mistakes to watch for
- Thinking a triangle turned upside down is no longer a triangle.
- Calling every four-sided shape a square.
What to practice before and after naming 2d shapes
- After: types of angles, once this one is mostly right.
- Learn it first: the naming 2d shapes lesson and the basic 2d shapes chart.
