Hello there!
Today I am going to put a number of maths puzzles here and you can all answer in the comments. Unfortunately, no gave there own one yesterday! I will put the challenges you make on this blog as long as you send them to me. Otherwise, I am happy to make my own (they are very fun to make).
I am thinking of a number:
That one is very difficult. To make it even more challenging- YOU ONLY GET TWO GUESSES so you should check your answers and make sure it is right before you post in the comments!
Also:
How many triangles can you see?
You get as many guesses as you want for this one but I will only answer ‘correct’ or ‘incorrect’. No hints!
If you have any questions then as always please comment below or email me! I can give feedback on the writing competition plans or writing in general and I would love to see any extra work you have been doing so please send them as well!
Speak soon,
Patrick

Good job Davmie- I like that definition.
Have a good think about the number. Maybe make a list of possibilities like we did in class and get rid of the ones that it couldn’t be.
As for the triangles, unfortunately 5 is incorrect.
Would you be able to give me some examples of prime numbers as well?
Start with the square numbers as that will give you few options to eliminate
There are 7 triangles?
prime numbers:
2, 3, 5, 7, 9, 11, 13, 17, 19, 23,?
and just realized the prime numbers are odd but only the 2 is even.
9 is not a square number as it has more than 2 factors: 9. 1 and 3
The rest are correct though! Good job!
There is only one answer remember Davmie! You also only get two guesses so try to narrow it down!
Unfortunately not Sophia! I’m going to post it again tomorrow so we will have extra time!

A prime number (or prime) is a natural number greater than 1 that has no other Factors other than 1 and itself.
Hmm.. i’ll have to think about that number your talking about, because it seems real hard.
And are there 5 triangles?
