Week 1 A Place To Stand Day: 2

Activity 3: Weird and Wonderful [10 points]
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).


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?So to solve out this problem we are gonna have to use multiplication. First we are gonna have to multiply 3 ml by the amount of days in a year which is 356. But if you don’t know how to multiply 3ml and 356 straight away, then try using place value partitioning. And now, Here is the problem solved with place value partitioning.3ml x 356= ?(300 x 50 x 6) x 3ml. 300 x 3ml = 900, 50 x 3ml= 150, 6 x 3ml= 18900 + 150 + 18=1068

  1. Kia Ora Mathew,
    Thanks for completing another activity!
    You did well on using place value partitioning to solve this problem. Next time make sure to use one line for each step so you post has more clarity and it can be more appealing for the readers. Remember that everything you post in here can be seen by anyone in the world so it is important that you keep that in mind when you write your content.
    Great job and keep up with the good work!

    Kia kaha,
    Patricia
