Number Talks with Mrs Madden

We were very lucky to have Mrs Madden come into our classroom yesterday and show us how to have 'Number Talks' in Maths.

She gave Room 5 the problem 18 x 5. Look at how many strategies we came up with. I wonder if our friends or whanau use any of these strategies or perhaps they have some other ones. It would be interesting to find out. Post any other strategies you can come up with in the comments...
