Abstract: Most teachers of primary mathematics are very familiar with worksheets which are used extensively to supplement the workbooks published by the Curriculum Development Institute of Singapore (CDIS). At primary levels, these worksheets are usually problem sheets where pupils do their working on the worksheets themselves, very much like pages of the workbooks. For mathematics at secondary level where the working has to be shown, problem are usually solved on separate sheets of paper and it is therefore unnecessary to provide space on problem sheets students to do the problems.

However, it is proposed that worksheets can be used effectively for various purposes at the secondary level and it is the objective of this article to discuss how secondary mathematics teachers can design and use such worksheets in their classes. One should be clear that a worksheet for secondary mathematics should not merely a list of problems (similar to tutorial problem sheets at junior college level) but, by its very name, should be for pupils to do the working on the worksheets themselves.
