A good starter/ group activity with key structure related words and questions provided.
You can rig it so a certain group wins or make up different questions.
Students could make up questions as a flipped learning activity
I have made several different grids that can be printed and laminated so used multiple times and a set of example questions.
This activity is part of a whole unit of work on Structures and the Built Environment which can be purchased as a bundle in my shop but also used on its own
