## Quality of Instructional and Practice Exercises: Superior (3)

There are many equations in which students can test the validity of their statements, though all equations are connected to one another. For example, determining the value for the fruits for one equation directly affects all other equations. Students may have to return to earlier equations they thought they had solved and modify their answer. Thus, there is a lot more work for students to do than first appears.

## Opportunities for Deeper Learning: Superior (3)

This activity provides space for students to create arguments and test the validity of statements. They can argue their validity based on how each equation fits into the whole set of equations.
