Tens and ones for Class 1

What tens and ones mean, one worked example step by step, and 5 questions to try. No timer, no account.

What it means

Every two-digit number is made of tens and ones. One bundle holds ten ones. Count the bundles first, then the loose ones: 4 bundles and 3 loose ones make 43.

Worked example: 43 = 4 tens + 3 ones

  1. 1Group 10 ones into one bundle. One bundle is 1 ten.
  2. 2Count the bundles: 4 bundles = 4 tens = 40.
  3. 3Count the loose ones: 3 ones.
  4. 4Join them: 40 + 3.

4 bundles of ten3 loose ones

So 4 tens and 3 ones = 43.
