About Teen Numbers

What this skill is

Teen numbers (11 through 19) represent a full group of ten plus additional ones (14 is 10 plus 4). Students practice building teen numbers using ten frames, base ten blocks, and number bonds.

When children learn it

Teen number structure is taught in kindergarten and early 1st grade, aligned to Common Core standard K.NBT.A.1.

Teaching Tips

  • Fill a full ten frame first before adding extra dots for teen numbers.
  • Say ten and four is fourteen to reinforce place value composition.

Common Mistakes

  • Writing teen numbers backward (writing 41 instead of 14).
  • Viewing 14 as 1 plus 4 rather than 10 plus 4.
