Description
- Overview:
- Inequalities are mathematical statements that connect unequal expressions.
This curriculum guide will help students understand inequalities, and be able to differentiate between inequality signs. They will solve inequality problems, being able to recognize problems where the inequality signs will need to change to arrive at a solution. Students will represent inequality solutions on a number line.

Quality of Assessments: Limited (1)
The first activity about notice/wonder here is a good chance to encourage curiosity. I wonder how can the others be evolved a bit so students are challenged more to explain their thinking and share their strategies with others.

There are some good videos here that could be useful with guiding prompts for what students can reflect about and share after watching. I think a challenge can be if adult learners would engage with videos that seem geared towards a younger audience.

This is a good start to understanding inequalities with good explanations and opportunities for practice. I think there's a bit too much focus on memorization and practice without the conceptual understanding. It might be helpful if it included ways to build a deeper understanding of what inequalities are, how they are useful, and how they tie into other concepts.
In addition to helping students to see a lot of examples of how inequalities look on a number line, this guide also points to a good resource that would be useful in helping teachers to build background knowledge: Resource 6.

Quality of Explanation of the Subject Matter: Superior (3)
If all of the resources in this guide are utilized, students will gain an understanding of how to graph inequalities on a number line, as there are numerous videos and visual examples.

Quality of Technological Interactivity: Strong (2)
This resource includes links to several interactive resources that would most likely engage students and are directly related to learning, but teacher direction and monitoring would be required for some of them.

Opportunities for Deeper Learning: Strong (2)
There are opportunities for deeper learning if the teacher using this guide delves into the lesson referred to in Resource 1. The guide itself, only refers to the video component of the lesson.

Quality of Instructional and Practice Exercises: Superior (3)
If students work through all of the resources noted in this guide, they would get sufficient practice in learning how to graph an inequality on a number line.

There are a lot of good resources linked to in this guide to help students gain understanding of inequalities, but some of the resources lack sufficient guidance for implementation in the classroom.
Hello Heidi,
I have added one more resource, resource number 6, from Lumen Learning. It has lessons and about 13 videos that will help students understand the concept of inequalities. It has both single-step and multiple-step approaches.
In addition to using the number line to represent solutions to inequality problems, this resource also shows how to represent inequalities using interval notation. Students can solve and see solutions. This resource allows for deeper learning and it worked for my students.
I will appreciate it, if you could go over this resource.
