Practice solving problems constructing triangles.

Practice plotting points to construct a scatter plot. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Students practice constructing scale drawings.

Practice problems interpreting linear expressions.

Explore a basic pattern to practice writing expressions. In collaborative groups, learners examine a contextual pattern and write an expression to model it. The task encourages groups to describe the pattern in multiple ways.
