B. Developmental Activities
1. Presentation
Peter has to clean 4 windows from four rooms.
How many windows does Peter have to clean?
Discuss
the following questions:
1.
Who cleaned the windows? Why do you think he has to clean windows? Why is
cleanliness important?
Let
pupils formulate mathematical expression to solve the problem.
Ask: What
mathematical phrase can be used to solve the problem? What makes your sentence
true? What sign is used to show that your sentence is true?
Discuss
that a mathematical sentence showing equality is called equation.
Let
pupils realize that 16 is the product of 4 x 4. Discuss that 4 x 4 can be
expressed as 4^{2}. Explain to the pupils about base and exponent.
