Teaching 4.NBT.A.2 – Read & Write Multi-Digit Whole Numbers Using Numerals, Number Names & Expanded Form & Compare Two Multi-Digit Numbers

Number & Operations in Base Ten – 4th Grade

Generalize place value understanding for multi-digit whole numbers.

Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

Teacher Notes
The teacher needs to understand how the value of a digit can help students compare numbers.  Knowing the relationship between two numbers helps students to organize, classify, and interpret numbers and data, and thus it makes it easier to compare numbers and problem solve.
