About this worksheet
Each worksheet has 6 problems choosing which set of two-colour counters models a given integer expression.
This worksheet runs the counter model the producing way: an expression is given and the student picks the picture that shows it. Every option holds the same number of counters, so the question cannot be answered by size - the wrong ones read the two numbers in the wrong order, or ignore the signs and make everything one colour. Sheets can be customized, turned into flash cards, or assigned for online learning.
Student objectives
- Match an integer expression to a counter model.
- Use the sign of a number to decide a counter colour.
- Reject a model that ignores the signs.
Everyday practice
- Say which colour stands for a negative.
- Build a model for an expression with two colours of objects.
- Explain why order of the two numbers changes the model.
