Part of: Work with numbers 11-19 to gain foundations for place value — 1 of 1 cluster items

Compose and decompose numbers from 11 to 19 into ten ones and some further ones

K.NBT.A.1

**K.NBT.A.1**: Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

What you'll learn

  1. Represent any number from 11 to 19 as a group of ten ones and some additional ones using physical objects
  2. Decompose a teen number into ten ones and some further ones (e.g., 14 is 10 and 4)
  3. Compose a teen number by combining ten ones with additional ones (e.g., 10 + 6 = 16)
  4. Record a composition or decomposition using a drawing or equation (e.g., 18 = 10 + 8)
  5. Explain in their own words that every teen number is made of "ten and some more"
