Math

                                                                 MATH

Last week for math we did a grid thing that we had to work out the coordinates and use a compass. We had to rite down a question and ask someone to try and work it out. Here is a picture of it in my book.

Here is the back where the answers to the questions are.

The work i have been doing in my group is ratios.Ratios are for knowing how much you need if you double or triple or anything like for example  

In a pool you need 3 litres of water and 2 cups of chlorine in the pool so as a ratio it will look like this.

                                                    3:2                                                   
and if you were to triple it all you do is 3x3 and 2x3.So the answer would be:                       9:6
