Candles on the cakes

We have been solving the maths problem 'Birthday cakes'.


Anna’s mum used 12 candles on 3 birthday
cakes.  How many candles could there be on
the cakes?

These are some of the ways we solved the problem...

  1. Kia ora Room 7,
    Thank you for sharing your math learning on your class blog. It is great to see the pictures of the various ways you worked out your problem. So many different ways to solve one problem! I can see that
    6 + 3 + 3 = 12
    3 + 4 + 5 = 12
    but I am not so sure about your bottom picture - you may like to check. Do you think 5 + 4 + 2 = 12?
    Keep up the great work mathematicians!
    Ngā mihi

    1. Hi Tania, thank you for commenting on our class blog. We had to think very hard to find ways to solve this problem (I think one of our counters slipped before we took the photo, you can see we wrote 2=5=5+12).

  2. Room 7, Wesley Primary School says, you did a nice try with your maths problem. Room 7 also tried the problem and we put 4 candles on each cake. We had 12 candles altogether. We like how you tried lots of different kinds of ways to solve the problem.

    1. Hi Room 7, we've also been working on this maths problem which you may like...

      I picked a big bunch of flowers to put on the Room 7 tables. There were 15 flowers and 4 vases. How many flowers might there be in each vase?

      We are figuring out the different ways to group the flowers.
