Over the last few weeks we have been looking at some rich maths questions, where students are required to problem solve and use a range of different mathematical strategies to find the answers.
Here is one to have a go at, you could even do this with your whānau at home to see what mathematical strategies they would use.
When I went into a classroom earlier this week a child rushed up to tell me she was 8 that day!
If you are 8 then this could be for you, but if it is another number then you just change the 8 to whatever your age is today.
Find a great variety of ways of asking questions which make 8 .
(If 8 is the answer, what is the question?)
Things like 6+2 , 22−14 , etc.
But you need to get examples that use all the different mathematical ideas that you know about.
Have a go and comment your answers onto the blog! :-)
