  • Walt:

    To understand Ratio and proportion.

    Task: Let us look at the end product y = mx+c

     Prior knowledge: 

    BEDMAS, highest common factor, lowest common multiples.

    Using common factors to factorize and expand.

    Simplifying fractions to reduce the numerator as 1 to get unit rate.

    . Expression: done

     Equation: done. Coeffecient, pronumeral, constant. Done

    equivalent fractions: Done

    Enlargement: Right angled triangles. 

    Ratio: done, proportion: - right angle triangle

    rate: as m as in y=mx +c. 

    Independent variable x axis /Dependent variable  y axis: Graphs

    Rise/run: rise y axis, run x axis:: graphs

    Unit rate: rise /run: graphs

    Gradient: done (m) positive and negative gradient:  Graphs.

    S/C: Using y=mx+c to solve problems in context.
