Sorting, Grouping and Comparing

We looked at the ways that we could sort ourselves into groups.

10 boys and 10 girls


10 in Kawatiri and 10 in Mawhera

10 Year 3s and 10 Year 2s

14 kids from last year and 6 new kids

Eleven 6-year-olds and nine 7-year-olds
(one 6-year-old is in the wrong line!)

How many students are in B4?
What are the all number pairs (number bonds) that equal that number?
Are there other ways we could group ourselves?

      Dear Paige
      How great that you are commenting from home.
      I wonder if you can figure out who got mixed up? (But don't use a proper name, we don't want any hurt feelings!)

      Can you think of any more ways B4 kids could group themselves?

      Dear Ian
      Well done for 15 correct pairs!
      Can you spot the equation that doesn't fit in though?

      Great work

    Hi when i was at school in the 70s,we did not have computers until we got to High school.We didn't have to wear a uniform untill High school.
    We had a lunch order once a week and it was just fish"n"chips,if we were naughty we would get hit with a ruler or a strap or the duster thrown at us.
    We only had blackboards.
    We would write in pencil till we got to form one then we would write with blue pen.
    Thanks Mel Deans
