Bundle 10 ones into a ten

Understand that a bundle of 10 ones equals 1 ten, and represent numbers as bundles.

Ten ones can be bundled together to make one new unit called a ten. It is like trading ten pennies for one dime -- the amount is the same, just packaged differently.

This bundling idea is the heart of how our number system works. Once you have ten ones, you trade them in and start a new bundle.

📋 For the teacher
Teach it (10–15 min):
  • Use real countable objects (beans, straws, blocks) and actually bundle ten with a rubber band or twist tie.
  • Connect to money if it helps: ten pennies trade for one dime.
  • Practice building several numbers this way: bundle ten, then count the loose ones left over.
  • Keep saying "ten ones make a ten" until it feels obvious, not just memorized.
Talk about it:
  • What happens when you get ten loose ones?
  • How is bundling like trading pennies for a dime?
  • If you have 1 ten and 6 ones, what number do you have?

Mastery looks like: They bundle ten single objects into a ten and read the resulting two-digit number.

Common stumbles: Bundling the wrong amount, not exactly ten; miscounting the loose ones left over after bundling.
