What Is Benchmark MA.3.NSO.1.2?

Four-digit numbers can be built from thousands, hundreds, tens, and ones in many ways. For example, 5,783 is 5 thousands + 7 hundreds + 8 tens + 3 ones, and it is also 57 hundreds + 83 ones.

Students show these ways with base-ten blocks, drawings, and equations. This flexible thinking makes regrouping in addition and subtraction much easier.

Official benchmarkCompose and decompose four-digit numbers in multiple ways using thousands, hundreds, tens and ones. Demonstrate each composition or decomposition using objects, drawings and expressions or equations.

On the FAST test: part of the Grade 3 reporting category Number Sense and Additive Reasoning, which is about 23–29% of the test.

Worked Examples

Worked Example 1

Show 3,452 Two Ways

Show 3,452 using place value in two different ways.
  1. 1Standard way: 3 thousands + 4 hundreds + 5 tens + 2 ones.
  2. 2Another way: 3 thousands and 4 hundreds is 34 hundreds, and 5 tens and 2 ones is 52 ones.
  3. 3Check: 3,400 + 52 = 3,452
Answer: 3 thousands + 4 hundreds + 5 tens + 2 ones, or 34 hundreds + 52 ones

Worked Example 2

Counting Hundreds

How many hundreds are in 2,600?
  1. 1Each thousand is 10 hundreds, so 2 thousands is 20 hundreds.
  2. 220 hundreds + 6 hundreds = 26 hundreds
Answer: 26 hundreds

Common Mistakes to Watch For

Using the hundreds digit as the total number of hundreds

Wrong:4,800 has 8 hundreds

The hundreds digit only shows the hundreds left after the thousands. In all, 4,800 has 48 hundreds.

Thinking a number can only be shown one way

Wrong:6,215 can only be 6 thousands + 2 hundreds + 1 ten + 5 ones

It can also be 62 hundreds + 15 ones, or 621 tens + 5 ones. The value stays 6,215.

Helpful Math Tip

Ask your child to show a number with play money: thousands as $1,000 bills, hundreds as $100 bills, and so on. Then trade one $1,000 bill for ten $100 bills and check that the total is the same.
