From our teachers' playbook

Ten times bigger, every single step

What do 4th graders learn about base 10?

The big idea of 4th grade base ten: every place is ten times the place to its right. The 7 in 700 is ten times the 7 in 70. Fourth graders read and write numbers up to 1,000,000 in standard form, word form and expanded form, like 46,203 = 40,000 + 6,000 + 200 + 3. They compare big numbers with >, < and =, and round to any place. The click moment is when kids see why the pattern works, so they can handle numbers far bigger than any they've built with blocks.

Our favorite ways to make base 10 stick

Big numbers get less scary when kids see the pattern. These are the moves we use every year.

Stack the places

Have kids build a number on a place value mat, then build it again one place to the left. Ask "What happened to the value?" Watching each digit become ten times bigger makes the rule something they discover, not memorize.

Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.

Read it four ways

Model one number on the board in standard, word, expanded and place value chart form. Point to how each form shows the same value. Then give partners a new number to write all four ways.

Why it works: handing over the work step by step, from teacher to student, is one of the most widely used teaching frameworks (Pearson and Gallagher, 1983).

Thousands warm-up

Start class with three quick questions: "What is the value of the 5 in 85,312?" Kids write answers on whiteboards. A daily two-minute check builds fluency before rounding and comparing.

Why it works: researchers who compared ten study methods found practice testing is one of the two that work best (Dunlosky and colleagues, 2013).

Questions parents and teachers ask about base 10

What is base 10 in 4th grade math?

Base ten is our number system, where each place is worth ten times the place to its right. Fourth graders use it to read, write, compare and round numbers up to one million.

What is expanded form?

Expanded form shows a number as the sum of the value of each digit. For example, 3,482 = 3,000 + 400 + 80 + 2.

How do you round to the nearest thousand?

Look at the hundreds digit. If it's 5 or more, round up; if it's 4 or less, round down. So 6,700 rounds to 7,000 and 6,300 rounds to 6,000.

How can I practice base 10 at home?

Use real big numbers, like the population of your town or the miles to a vacation spot. Ask your child to read it out loud and tell what each digit is worth.
