MARS: algebra: inequalities
This collection features four resources on the topic inequalities.
The resources feature:
- Concept development lessons that focus on developing conceptual understanding of significant mathematical ideas.
- Tasks that provide mathematically rich problems that come with work for students to peer assess.
The Mathematics Assessment Resource Service (MARS) is a collaboration between the University of California at Berkeley and the Shell Centre team at the University of Nottingham, with support from the Bill and Melinda Gates Foundation. The team is known around the world for its innovative work in maths education.

Linear and exponential models
This short task asks students to identify linear, exponential growth, and exponential decay from tables of values. Students then sketch the graphs and identify the equation representing the linear relationship.
This is a short task from the Mathematics Assessment Resource Service, a collaboration between UC...
Evaluating statements about number operation
This resource develops the concept of substitution of integers, fractions, decimals, and directed numbers into inequality statements in order to test their validity. Students also represent inequalities algebraically and in words.
An initial question that students work on is representing the statement
...Representing inequalities graphically
This resource develops the concept of representing inequalities on a Cartesian coordinate grid. Students work with algebraic representations in a variety of formats and then shade the relevant areas.
An initial activity is to play a game ‘Hunting the target’. This involves students being given inequalities...
Reasoning with equations and inequalities
This short task considers reasoning with equations and inequalities. Students answer a series of six questions, including working with solution sets for pairs of inequalities, and sketching the solution set of a system of four inequalities.
The resource comes with a detailed rubric for each question.
