Activity 3: Flying Fungi [10 points]
In the middle of winter it can get quite wet and damp in New Zealand, can’t it? When it gets really damp, it is common for things like mould and fungi to start to grow. We can often see them on the walls, ceilings or floors of our houses or outside on footpaths, buildings or roadways. Some types of mould and fungi are so small that they can’t be seen. Some of these tiny fungi/mould can be found in the air. They are called ‘airborne fungi’ and they can be unhealthy for us.
Let’s imagine that we tested the air in your classroom and found 7 different kinds of mould. Eek! The cleaner says that it takes 5 days for each mould to be eradicated (removed). If the school had to remove each mould one at a time, how long would it take to remove all the mould from the classroom?
On your blog, tell us how you would solve this tricky maths problem. Be sure to also post your final answer in days or weeks.
I would do 5 x 5 = 25 and 2 x 5 = 10 then 25 + 10 = 35.
Hi Michael
ReplyDeleteWell done on solving this problem. I really like how you broke down the problem into easy to solve sections. Breaking down maths problems like this will allow you to solve even harder problems.
Now that you have reached the answer of 35 can you think of any other times tables that you can use to solve it?
You only have a few activities left to complete before you are completely done. Great work! I hope you go back and complete them so you can get full points!
Ngā mihi,
Izzy
