With base ten blocks, build representations of three-digit numbers using hundreds, tens and ones.

Clarifications:

Essential Understandings

Concrete:

  • Using base ten blocks, identify that a unit cube will be used to represent ‘one’. A rod will be used to represent ‘ten’ because it is a bundle of ten ‘ones’. A flat will be used to represent ‘one hundred’ because it is a bundle of ten ‘tens’.
  • Match the given three-digit number to the correct combination of base ten blocks.
  • Given a three-digit number, use base ten blocks to represent the given number.
Representation:
  • Using a visual representation of base ten blocks, identify that a unit cube will be used to represent ‘one’. A rod will be used to represent ‘ten’ because it is a bundle of ten ‘ones’. A flat will be used to represent ‘one hundred’ because it is a bundle of ten ‘tens’.
  • Match the given three-digit number to the correct visual representation of base ten blocks.
  • Given a three-digit number, create a visual representation of base ten blocks to represent the given number.

Date Adopted or Revised: 06/14 Cluster: Understand place value. (Major Cluster) : 

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Name Description
MAFS.2.NBT.1.1: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
  1. 100 can be thought of as a bundle of ten tens — called a “hundred.”
  2. The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
