01

What Students Need to Do

Students read, write, build, and break apart numbers from 100 to 999. They explain how each digit represents hundreds, tens, or ones.

02

What Mastery Looks Like

Given any three-digit number, a student identifies each digit’s place and value. The student represents the number with blocks, drawings, words, and expanded form.

03

Common Misconceptions

Students may say the 6 in 364 is worth 6 instead of 60. They may ignore zero as a placeholder or reverse digits when moving between forms.

04

How to Assess It

Exit ticket: Show 472 with a drawing, write it in expanded form, and state the value of the 7.

1. 01

   Build three-digit numbers with base-ten blocks, then trade 10 ones for a ten and 10 tens for a hundred.

2. 02

   Ask, “How can 364 be broken apart?” Students write two decompositions and explain how each keeps the same value.

3. 03

   Play Place Value Draw: students draw three digit cards, build the largest number, and justify each digit’s position.

4. 04

   Use store inventory labels, such as 248 pencils, and have students state the hundreds, tens, and ones represented.

• MA.4.NSO.1

  Understand place value for multi-digit numbers.

• MA.1.NSO.1

  Extend counting sequences and understand the place value of two-digit numbers.

• MA.5.NSO.1

  Understand the place value of multi-digit numbers with decimals to the thousandths place.

• MA.3.NSO.1

  Understand the place value of four-digit numbers.
