For a week we have been doing, in Project maths a thing about a pool table.

How it works is there is a grid and you need to see how many bounces it will take until the ball goes in, you need to go though the square on the grid by a 45 degree’s. It can only turn when it hits a wall. To finish you have to get the ball in any of the 4 corners. The first lesson we had a lot of different grids on a piece of paper and we had to do them and find how many bounces it will take. I was sick for some lessons so I was only there for 2 lessons, other then the first lesson I was also there on the last lesson and the teacher told everyone the formula I was so confused how to do it at first but I slowly worked it out with some help.

The formula can be hard to learn but it will turn easy once you understand it. So first you pick the grid like 45 by 65 then you find a number that goes into both like 5 you would then count how many 5’s can go in each like 5, 10, 15 and so on. For 45 its (9) and for 65 its (13) then you see if you can put any other number into that and there is only 1’s which you don’t use so then there is no other ones so you plus the 2 numbers like the 9 and the 13 so 9+13=22. The next step is to -2 like 22-2=20 so that’s the answer of how many bounces the whole number sentence is 9+13+22-2=20 if you want to check your answer you can use maths 300 that’s what I did.

A part I found challenging was finding out how to do the formula.
