In this Unit of Study…
Students will count, locate, and order numbers 0-20 on a number line. Students will create concrete and pictorial sets to show they understand the concept of greater than or less than and the exact same amount as a given set of objects up to 20. They will extend this concept to written numerals. Students will demonstrate that they can utilize comparative language when comparing sets or numerals up to 20.

- MA.K.NSO.1.4 Compare the number of objects from 0 to 20 in two groups using the terms less than, equal to, or greater than.
- MA.K.NSO.2.3 Locate, order, and compare numbers from 0 to 20, using the number line and terms less than, equal to, or greater than.
- MA.K.NSO.3.2 Add two one-digit whole numbers with sums from 0 to 10 and subtract using related facts with procedural reliability.
Key Concepts:
- Fluency: One more/ one less, zero more/less
- Locate and order numbers 0-20
- Compare numbers to 20
