What mastery looks like

  • Write 5 as 5/1 and explain why
  • Locate 4/4 and 1 at the same point on a number line
  • Identify which fractions from a list equal a whole number: 6/3, 8/4, 5/2

Check your understanding

If you ask Fractions of a whole (age 8+) to write the number 3 as a fraction, can they write 3/1 — and also tell you what fraction equals exactly 1 whole, like 4/4 or 5/5?
