**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.

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