A message from Patrick- 7th May 2020
Good day to you all!
I hope we are having a fine week and that you managed to find time to enjoy the beautiful weather!
Today I am going to repost the Math challenge from yesterday. I have to say I was a little disappointed with the lack of response and so, if there is not higher participation from today, I will send it over to the year 6s! I’m sure they will give it a good go.
First of all, I will give you some of the triangles from this image
The first 6 triangles are as follows:
There are many, many more to count! This should give you a hint as to how to do it.
Secondly:
I am thinking of a number:
- It is a three digit number
- It is less than the product of 8 and 25 (8×25)
- It is a square number (eg. 2×2=4, 4×4=16, 9×9=81, 15×15=225…)
- The factors of this number are prime numbers themselves (please comment what the definition of a primer number is)
- All three of its digits add up to more than 5
This time I will give you as many guesses as you want and if you are not correct then I shall let you know which rule your answer does not fit and why!
I want a lot more this time year 5! I know it is difficult but “it matters not how strait the gate, how charged with punishments the scroll” (finish the quote)!
Remember to always remain respectful and kind and I looking forward to speaking to you all!
Take care,
Patrick

Are there 13 triangles?

No- there are still quite a few more.
I’ll post the full explanation tomorrow morning so try to get it before then!

It’s not 165 Weda- Yi Sheng has put the correct answer above!
For the triangles look at the bit I have added. There are more than 6!

There isn’t! You’re the closest yet though Davmie!

Have a look at my latest post! It explains the whole conundrum.

Is it 169 and a prime number is a number that only has two factors.
