This week for math we wrote the top ten teams from 1896 - 2012 and 2016. We had to plus all the medals they won in total the one that had the most was USA. we added New Zealand as well they got 105 in total. New Zealand have won 15 medals in the present. This activity is interesting because it helped us with our addtion. NZ got 105 in total.       

Olympics Challenge 1

 LI: To solve how many meters and strokes Michael Phelp did.

The most efficient strategy I used to solve this challenge was addition and division. Addition strategy was used to find out how many meters Micheal swam for all of his different events, and the division strategy was used to find out how many strokes he did if he took 2 meters in each stroke. 

Steps:

For or the freestyle relay (4x100m), we didn't multiply it, the 4 is the amount of people that did it so Michael was 1 of 4 so it is 100 same for the medley relay and the second freestyle relay. 

The maths:

 400

 100

 200

 200

 200

 100

+100

-----------

1500

Then, I divide 1500 by 2 because for every stroke Michael takes it is 2 meters. 

1500 divided by 2 = 750

So 750 is the amount of strokes to take Michael over to the end of the pool

I enjoyed doing this activity because it helped me improve my division skill.
