This lesson module allows students to explore the meaning of inequalities. After this lesson, students should be able to understand that there are multiple solutions to an inequality. It contains a formative assessment matching activity at the end and a critical thinking closing activity.

In this assessment students will be assessed on one to one correspondence, cardinality, writing numbers and comparing sets of objects. Students will be given two mystery bags that contain up to ten objects. Students will count and record the number of objects found in each bag. Students will be asked to circle the greater number and are asked how they know the number is greater. Teachers will need to prep the mystery bags. This is a whole or small group activity. A rubric and assessment task sheet are available.
