To train pupils to solve problems by the method of counting and attempt to guide pupils to generalise the patterns in calculation so that they can solve more complicated problems, and hence develop their critical thinking skills, numeracy skills, problem-solving skills and study skills.
To train pupils to analyse problems involving sums and differences of numbers with the help of diagrams and generalise the patterns in calculations, in order to solve more complicated problems, so as to develop their critical thinking skills, numeracy skills, problem-solving skills and study skills.
Previous Knowledge: arithmetic operations
Perimeters and Areas
To train pupils to use the formulae for calculating the perimeters and areas of squares and rectangles to solve more complicated problems that involve perimeters and areas, and attempt to guide pupils to generalise the patterns in calculations from simpler problems so as to develop their critical thinking skills, numeracy skills, problem-solving skills and study skills.
Previous Knowledge: Concepts of perimeters, perimeters of squares and rectangles, areas of squares and rectangles
Problems on Multiples
To train pupils to use the concept of multiples and techniques in carrying out arithmetic operations to solve problems involving multiples using the most effective method, and attempt to guide pupils to generalise the patterns in calculations from simpler problems so as to develop their critical thinking skills, numeracy skills, problem-solving skills and study skills. Their communication skills can also be developed if the worksheets are completed through group activities.
