1.N.1.6 Compare and order whole numbers 0-100.


In a Nutshell

By the end of first grade students can use place value knowledge to compare and order numbers up to 100. When working with numbers they describe the relative magnitude of numbers using words such as equal to, more than, less than, fewer than, or about the same as. Students should be able to sequence a set of numbers in order from least to greatest and greatest to least. Comparing and ordering numbers is a fundamental skill for understanding place value and building a strong foundation in number sense.

Student Actions

Teacher Actions

  • Develop strategies for problem solving as they describe whole numbers by their relatives size using words such as equal to, not equal to, more than, fewer than, about, and same as to tell about a given number.
  • Make conjectures, model, and communicate mathematically about their thinking as they place numbers in correct order of numerical value from greatest to least and least to greatest and explain their reasoning behind their order. Students can use manipulatives such as an open number line to help order numbers. (An open number line will help build the idea of relative size.)

  • Develop a deep and flexible mathematical understanding as they construct examples, models, and drawings while using hands on manipulatives to explore ways to compare and order whole numbers 0-100. 

  • Implement tasks that promote reasoning and problem solving by choosing problems that allow multiple entry points and varied solution strategies during exploration of ordering numbers while providing hands on manipulatives to further students understanding. One example might be to use 10 number cards to explore ordering greatest to least.  This game can easily be differentiated for learners.
  • Posing purposeful questions to help students use prior knowledge and reasoning in order to place numbers in numerical order. What number is the greatest? Least? What tool did you use to help you put these numbers in order? Does it look correct? Anyone disagree?  These questions can also be used to assess number sense and ordering strategies.

  • Build procedural fluency by providing games and activities to be used with whole and small group instruction that challenges students to think deeply about comparing and ordering numbers while offers multiple approaches to solutions. Providing a variety of opportunities for students to participate in these tasks will build conceptual understanding

Key Understandings

Misconceptions

  • Develop understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections.

  • Construct, interpret, and describe a model representing numerals in a linear way. 

  • Only the digit in the ones place is used when comparing and ordering numbers.  
  • Tens and ones place can be used interchangeably when representing numbers.

  • A number, for example, 54 can only be represented as 5 tens and 4 ones.
