From our teachers' playbook

Cubes, rods and flats, oh my!

What do kids learn about base 10?

Our number system is built on groups of ten, and base 10 is how kids learn that. They see that ten ones make a ten (a rod) and ten tens make a hundred (a flat). First graders work with tens and ones, second graders add hundreds, and older students stretch to thousands: 2,345 = 2 thousands + 3 hundreds + 4 tens + 5 ones. Base 10 blocks make the idea something kids can hold. The click moment is when a child trades ten little cubes for one rod and says "It's the same amount!"

How we teach base 10

Base 10 makes sense when kids touch it, draw it and then use it.

Trade up!

Give each pair a pile of cubes and a die. They roll, take that many cubes, and trade ten cubes for a rod whenever they can. First to make a flat wins. Trading over and over shows them exactly how our number system groups.

Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.

Quick place value checks

Play a short place value game at the start of math: "What is the 6 worth in 462?" Quick retrieval keeps the idea fresh, and kids love beating their own score.

Why it works: pulling an answer out of memory makes it stick far better than rereading it, one of the strongest findings in learning research (Dunlosky and colleagues, 2013).

Draw sticks and dots

Once kids know the blocks, have them draw a line for each ten and a dot for each one. It's fast, works anywhere and moves them from objects to symbols.

Why it works: children learn more from words and pictures together than from words alone (Mayer, 2009).

Base 10 questions from teachers and parents

What does base 10 mean?

It means our number system is built on groups of ten. Each place is worth ten times the place to its right: ones, tens, hundreds, thousands.

What are base 10 blocks?

They're math blocks that show place value: small cubes are ones, rods are tens and flats are hundreds. Big cubes show thousands.

What grade learns base 10?

Kids start in kindergarten with teen numbers as ten and some more. First grade covers tens and ones, second grade adds hundreds, and fourth grade extends to larger numbers.

Can I make base 10 blocks at home?

Yes. Use printable blocks, straws bundled into tens or even pennies and dimes.
