In This Unit of Study…

Students will plot, order, and compare numbers up to 100. They will use place value and models, including number lines, to compare whole numbers up to 100 by using comparative language such as greater than, less than, or equal to. Students will use the comparative language symbols >, <, and = to compare two numbers up to 100.

B.E.S.T. Benchmarks:

• MA.1.NSO.1.1 Starting at a given number, count forward and backwards within 120 by ones. Skip count by 2s to 20 and by 5s to 100. 
• MA.1.NSO.1.4 Plot, order and compare whole numbers up to 100. 
• MA.1.NSO.2.3 Identify the number that is one more, one less, ten more and ten less than a given two-digit number. 

Overarching Key Concepts:

• Fluency: Count on and back within 20 and skip count by 2s to 20 and 5s to 100.
• Plot, compare, and order numbers to 100.
• Identify the number that is one more, one less, ten more, and ten less than a given two-digit number.
