Primary Standards:
MAFS.K.CC.3.6 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.1
1Include groups with up to ten objects.
MAFS.K.CC.3.7 Compare two numbers between 1 and 10presented as written numerals.
Connecting Standards:
MAFS.K.CC.1.3 Read and write numerals from 0 1 to 20 10. Represent a number of objects with a written numeral 0 1 – 20 10 (with 0 representing a count of no objects)
Content Knowledge:
This Unit builds upon work done with comparing numbers through 5 in Unit 2. The concept of comparing should continue to be taught using the Concrete to Pictorial to Abstract model of learning. All students should begin comparing values by representing the values with concrete objects to build understanding. Once students demonstrate an understanding of the concepts of “more” and “less”, they can then move on to a more efficient strategy of drawing pictures. Some students may move through these strategies more quickly in this Unit, due to their understanding from Unit 2.
Ultimately, students will finally be able to compare the values represented by the written numerals. The goal is for students to be able to compare numbers 1-10 by the end of the kindergarten year. The timing on this will vary depending on the student.
GCG 1 – Learning Goal: As a mathematician, I will be able to use physical objects and pictures to compare quantities 0-10
- Step 1: Students can compare physical objects in 2 sets using various strategies (matching, observation, fair share, counting)
- Step 2: Students can compare physical objects in 2 sets using various strategies and use appropriate vocabulary – greater than (more), less than (fewer), equal to (same as) to compare
- Step 3: Students can compare pictures of objects using various strategies and use appropriate vocabulary
GCG 2 – Learning Goal: As a mathematician, I will be able to write numbers to compare quantities 0-10
