Dear Pupils,

I would like you to print out the questions below and try these problems on whole numbers on foolscap paper, using pencil! Remember READ, THINK, PLAN, DO, CHECK. Underline the important information that will help you to solve the problems. Present your model drawings and methods systematically.

Keep it neat and tidy!! I believe you can do it! You will submit your work on Friday! Thank you!

Food for thought: Success is a matter of understanding and religiously practising specific, simple habits that always lead to success!
