How about some amazing sums. Things like
1+2+3....+n = n(n+1)/2 (sum of n numbers)
1+2+3+4+5 = 5*6/3 = 15
1+3+5.....(2n-1) = n² (sum of n odd numbers)
1+3+5+7+9 = 25
1²+2²+3²....n² = n(n+1)(2n+1)/6 (sum of n squares)
1²+2²+3²+4²+5² = 5*6*11/6 = 55
There are tons of these scattered around on the web âº

i remember some of my math projects that were more fun involving krafts. you can use geometry to make a kite or some of those oragami balls. turn them 3d and just say theyre 3d objects! of course the easiest starting with a cube. so on. if you decide to make a kite, you can make it in the form of a triangle with straws and tissue paper. look it up on the net to see if you can find instructions. hope this helps '']

You may research non-euclidean geometry, where the parallel lines intersect. I think this is really interesting and it can kinda impress your class and techer.
