Concrete:

• Using base ten blocks, build a concrete representation of a two or three-digit number on a place value chart.
• Given the place value chart, identify the column that represents the greatest place value.
• Given two models of base ten blocks on a place value chart, compare the value of the numbers by starting in the greatest place value position.
Representation:
• Understand the following concepts and vocabulary: ones, tens, hundreds, place value, greater than, less than, equal.
• Given two numbers, compare the digits arranged in a place value chart to determine if a number is greater than, less than, or equal to another number.

 Number: MAFS.4.NBT.1.AP.2a Category: Access Points Date Adopted or Revised: 06/14 Cluster: Generalize place value understanding for multi-digit whole numbers. (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.
