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 42. Explain to the pupils about base and exponent.
