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.
To figure this questions out all I needed to do was multiple 5 by 7:
7 x 5 = 35
Since there are 7 days in a week it would take 5 weeks to remove the mould
Hello Alex,
ReplyDeleteIt looks like you've been working hard on this equation. You have gotten the answer completely right!
It's very scary for airborne fungi to be in your classroom because it is very bad for our health. It can cause many illnesses and sicknesses that could be very bad for your organs.
Maybe next time you could explain why you got your numbers.

Hi Alex,
ReplyDeleteIt is great to see how you've written down your strategy explaining to us which steps you have taken to solve this problem.
Writing down a number equation is always a good first step to take especially when you encounter (come across) a wordy question. Good thinking!
I like how you have given your answer in two different units. As you have mentioned, 35 days is exactly the same as 5 weeks - ka pai.
Do you enjoy problem solving? What sort of maths questions do you like to solve?
Keep up the good work,
Susie
Kia Ora Alex,
ReplyDeleteWell done for completing this activity. I finished this activity too. It's great to see you completing these activities during these summer holidays. Thanks for sharing your learning about this activity. Did you enjoy doing this task? I got the same answer as you. I also used the same formula as you too.
NICE:)
