Dear students Love it or hate it, mathematics is every where. It’s not just at school where you have to do sums, work out angles , follow plans and understand graphs. You use mathematics all the time: playing a computer game, shopping, backing a cake, reading a bus timetable, building a model aero-plane , things that everyone can do, and yet they all need just as much mathematics as your school homework.
Dear parents Always let your child do his/her homework him/herself. Your role is to encourage your child and reward your child for his/her effort.
Equipment your child will need A pencil for drawing An eraser for correcting mistakes Pen, ruler and sharpener
