What mastery looks like

  • Compose 14 as a group of ten and four ones using objects
  • Decompose 17 into 10 + 7 and record as an equation
  • Explain that 13 is 'one ten and three ones'

Check your understanding

If The teen numbers has 14 building blocks, can they see it as one full tower of 10 and 4 left over — understanding 'teen' numbers as ten-and-some-more?
