CAT Grade 10

In this lesson we revise how to factorise trinomials by focusing on the sum and the product of numbers, rather than using a diagram. Then we use this knowledge to simplify algebraic fractions.

In this lesson we learn how to multiply algebraic fractions by working with factors. We need to remember the difference between factors and terms to decide whether we can simplify a fraction or not. We establish the important concepts using numbers without any variables. Remember that when we multiply fractions, we multiply the numerators by the numerators and the denominators by the denominators. Then we move onto algebraic examples and show how to cancel factors with each other. Remind learners that what they are really doing is dividing through by the same factor in the numerator and in the denominator, which means that they are not changing the value of the expression. They are merely multiplying by 1 over 1, so the value of the expression stays the same.

This lesson concentrates on learning the various types of poems. We will look at poetic forms including features of ballads, odes, elegies and haiku. This lesson content is most appropriate for Gr. 10 learners.

This video deals with time. It looks at converting from different forms of time as well as converting from different time units. Later in the video they look at planners and calendars.
