How do you teach three-digit place value?

Extend the base-ten block model: ones cubes, tens rods, and hundreds flats. Have students build numbers like 253 using blocks, then write them in standard form, expanded form, and word form. Worksheets that move between these three representations build flexible understanding.

What is expanded form and why do second graders learn it?

Expanded form breaks a number into its place value components: 426 = 400 + 20 + 6. It shows what each digit is actually worth, which is essential for understanding addition and subtraction algorithms. Worksheets that ask students to convert between standard and expanded form reinforce this understanding.
