Lesson objective: Students apply their understanding of comparison of objects as they create a group and then compare their group to another group.

This lesson provides an opportunity for students to apply their knowledge and understanding of comparison to a real-life situation. Students are asked to collect ‘bugs’ by grabbing a handful of counters and compare them to a bug collection. They label both bug jars using comparison words, less than, or greater than. They consider what to do when the jars have equal amounts.

Key Concept students will use:

- Sets of objects can be compared using the language greater than, less than or equal to
- Matching, counting strategies and visual strategies can be used to compare quantities (up to ten) of two groups

Skills students will use:

- Count to tell the number of objects; (Grade K, Unit 1 and Unit 2)
- Understand the relationship between numbers and quantities; (Grade K, Unit 1 and Unit 2)
- Connect counting to cardinality; (Grade K, Unit 1 and Unit 2 )
- Count to tell how many; (Grade K, Unit 3)
- Understand that the last number name said tells the number of objects counted (cardinality) (Grade K, Unit 2 )

Students engage in Mathematical Practice 2 (Reason abstractly and quantitatively) as they make connections between the quantity and the numeral it represents. They also practice Mathematical Practice 6 (Attend to Precision) as they use correct mathematical compare vocabulary and label their comparisons correctly. Students will model a familiar situation as they compare bug collections. Students will use counting, matching and visually looking to determine which group is greater than and which group is less than.
