Odd and even number rules

Explain and use the properties of odd and even numbers when adding, subtracting and multiplying, e.g. odd + odd = even, odd + even = odd, and any whole number multiplied by an even number is even

Lesson

Set out your lesson

“Odd and even number rules means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”

Bring to the table

  • Small counters or grid paper
  • Paper and pencil
Extra for the adult

Worked example. Three rows of four counters make 12. Write 3 × 4 = 12.

Optional challenge. For Odd and even number rules, add one harder example after success.

What to notice. Keep one parent note: examples tried; results; support used. This session samples Odd and even number rules, not mastery.

Selected Default Gakuva

Odd and even number rules means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.

Materials: Small counters or grid paper; Paper and pencil. Adult models 3 × 4 as three groups of four, then writes the product. Child builds three multiplication examples as equal groups and records each product. Done: three correct products with groups matching the writing. Stop after the fresh check; keep optional challenge for another day.

Check understanding

  • Explain with paired counters why the sum of two odd numbers is always even
  • Predict without calculating whether 347 + 129 is odd or even and justify it
  • Explain why 6 x 37 must be even
“Without adding them up, can your child tell you whether 347 + 129 will be odd or even — and explain why?”
