Does anyone have any fun maths puzzles i could use? Not too difficult - for a group of fairly bright 14 year olds :)

OpenStudy (anonymous):

Yes, what what happens when an unstoppable force collides with an immovable object?

OpenStudy (anonymous):

^Not math ik

OpenStudy (anonymous):

haha that's funny :') but yeah i need them to be more maths related :)

OpenStudy (anonymous):

Try answering my alg. 2 test question im re-doing: Write an equation for the parabola with a vertex at (2, -1) and y-intercept 5.

OpenStudy (anonymous):

Oh "FUN" Didn't catch that.

OpenStudy (anonymous):

Haha! Yes quite short and fun please!

OpenStudy (anonymous):

What is i^27?

OpenStudy (anonymous):

OpenStudy (anonymous):

Any particular type of math puzzle? Geometry? Probability?

OpenStudy (anonymous):

Nothing in particular really.. one of the ones i'm doing, is \[x=\sqrt{6+\sqrt{6+\sqrt{6...}}}\]

OpenStudy (anonymous):

Prove Pythagorean theorem. :D

OpenStudy (anonymous):

I would but we've actually done that too many times now!

OpenStudy (anonymous):

Someone else did the question about the childrens ages, where the eldest child has a cat with a wooden leg, if you know that one?

OpenStudy (anonymous):

So a worded problem could be good :)

OpenStudy (anonymous):

How about this: a bear is facing south. He walks forward for a mile, then turns right 90 degrees. He then walks forward another mile, then turns right 90 degrees again. He then walks a final mile forward. The bear is still facing south. What color is the bear?

OpenStudy (anonymous):

Oh yes thankyou! I like that one :) Thanks for your help!

OpenStudy (anonymous):

No problem :) Feel free to ask if you need any more!
