Week 1, Day 2, Activity 3

New Zealand is just one of many countries that has amazing plants and trees. In fact, the African desert is home to some pretty incredible plants, like the cactus. Some cacti are able to survive on as little as 3 millilitres (ml) of water a day. Wow!
Let’s imagine that you are given a cactus for your birthday. To keep it alive, you must give it 3 ml of water every day.
Over one full year, how much water will you need to give your cactus plant?
On your blog, tell us how to solve this maths problem. You can write your answer in words, use a Sketchpad image, or post a video explaining how you would figure it out. Be sure to give us your final answer in millilitres (ml).

I solved this maths problem by going 365 x 3 = 1095 ml
I got 365 because that is how many days there is in a normal year.
If it was a leap year it would be 366 x 3 = 1098 ml because there is a extra day in a leap year.

    Great working out for this problem. I really like that you have put some thought into it and included the leap year answer. Not everyone has thought about that, so well done!
    It is not a lot of water each day but it adds up over a whole year. Three mils is less than one tea spoon full of water. Imagine if that was all we had to drink. Crazy to think that it gets so hot in the dessert and they only need such a small amount of water to survive.

    Great job Caitlyn, hope you are having a good holiday so far.

    Until next time

    Allie :)
