Maths Daily for Primary 6 – A Pen & Paper Exercise Preface This E-book is especially produced for the parent who has little or no time with the child during school days, the teacher who wants to consolidate the lessons taught, and the student who needs some kind of daily work schedule in practising Maths. All of you will find Maths Daily for Primary 6 – A pen & paper exercise useful with the little bit of time left in a day at school. You, the student, need not lug a thick text Maths book with you. You can access Maths Daily for Primary 6 – A pen & paper exercise anywhere anytime as long as you have it in your electronic gadget with you. It is recommended that you, the student, work through one practice exercise, or 10 questions, a day. The golden rules for achieving success in Mathematics using Maths Daily for Primary 6 – A pen & paper exercise are: ❖ Do ONE practice exercise per day and keep up this schedule. ❖ Do take out a pen and paper to work out each sum showing the working steps. ❖ Do keep a record of your written work via using a notebook or a simple exercise

book. ❖ You are not to just look at the sum and stare at it. You just have to take out a pen and

paper to work out each sum. That is as simple as that. ❖ Sports persons in any sport don’t just stare at their game and not practise. They just

have to practise. No Choice. ❖ Try NOT to skip even a single day. ❖ There are only 5 weekdays in a week – Mondays to Fridays. ❖ There is NO Maths Daily on weekends – Saturdays and Sundays. ❖ Do not attempt to accomplish 2 or 3 days’ work in a single day (and then not do

anything for the next few days)! ❖ If a day of practice is missed, skip that practice exercise. ❖ Not completing a day or two or three days’ work is fine. ❖ Just try not to make it too often. ❖ The key to success is consistent revision and consistent practice. ❖ It is recommended that this ebook/iBook be used together with other good

Mathematics books on the market. ❖ After all, practice makes perfect! ❖ All the best. Mrs Chan Laurie.
