Olympics Maths Challenge 1

LI. to use the most efficient strategy to find the answers.

LI. to use LS2 Maths Talk to discuss strategies.

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.
