Today we have learnt all about what a ‘mean’ average is. Some call this the trickiest or ‘meanest’ average because there is both addition and division involved in the calculations. We began by learning the method and then discussing how we can use the inverse to find a missing value – this was tricky but we got there! We then headed outside to collect our very own data. To do this we created our results table and then learnt how to triple jump, shot put and discus.

**We then used our data to calculate our own means!**

To me finding means was very nice because we got to learn what it means and we also got to find out how far we can jump for our means

We used different methods to calculate the answer to the sum. I really enjoyed the triple jump because we could find out how far we could jump.

In national numeracy day we were learning all about means.

So we were recording all the lengths we jumped 5 times each and then we worked out our own average means for example mine was 2.0

I think finding means was something very cool to learn

We used this method to calculate our groups mean by jumping as far as we can.

This lesson was really fun. I also thought the way we tested was fair because everyone had an equal amount of tries.

To calculate our means we had to add together all of our starting numbers and divide it by the number of people or objects that there are for example: 42+56 =98 and if there was 2 people , you would divide it by 2 ( 98*2 = 49 so there would be a mean of 49.

I really enjoyed the triple jump.
