Introduction asks students to brainstorm and identify as many different uses of percentages in everyday life. After this, students are introduced to the method of calculating percentages without a calculator, using 10% as the starting point and building block. (eg. Find 36% - first find 10%, then half 10% to find 5%, divide 10% by 10 to find 1%. So 36% = (3x10%) +5% +1%. Slides 28-33 are the worksheets.
