Rich maths questions!


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+22214etc.

But you need to get examples that use all the different mathematical ideas that you know about.

1) So you could show some multiplication and some division.

2) If you know about fractions then you can add or subtract numbers involving fractions. You could also ask questions like "What is half of 16?''; "What is four-fifths of 10?'' and so on

Have a go and comment your answers onto the blog! :-)
