### Other Examples:

- Moves a long unit block to be parallel with another block after adjusting the distance between them so as to accurately place a perpendicular block across them, in anticipation of laying several other blocks perpendicularly across them.

### Help your student become a(n) Implicit Angle User

A variety of construction toys such as blocks or toy train tracks invite children to make paths with turns and implicitly use angle concepts such as making the bottom of a building, laying long blocks alongside each other (parallel) and at a right angle (perpendicular). Discuss these situations using appropriate language. For example, talk about both the paths and the movement of vehicles on them, using the language of turns and angles ("that sharp angles means a big turn!") to begin to make the mathematics explicit.
