Tenths (age 9+)

Mathematics · Fractions · conceptual

Recognise and use thousandths; relate them to tenths, hundredths, and their decimal equivalents (e.g. 1/1000 = 0.001, 35/1000 = 0.035)

What mastery looks like

  • Write 0.025 as 25/1000
  • Explain that 1 tenth = 100 thousandths
  • Place 0.345 on a number line between 0.34 and 0.35

Check your understanding

If Tenths (age 9+) sees the decimal 0.003, can they write it as a fraction and tell you roughly where it sits on a number line between 0 and 0.01?
