Presentation transcript:

Mental Maths Warm Up WALT: I can state what fraction and percentage of a shape is shaded Example: Calculate how many squares altogether (2 x 5 = 10) Count how many are shaded (7) Represent this as a fraction (7/10) Convert into percentage (70%) Top Tip! Use your calculator to find percentages from fractions!! E.g. 7/9  (7 ÷ 9) x 100  77.8%

WALT: I can state what fraction and percentage of a shape is shaded D. B. E. C. Now, create your own shape in the back of your book. Find out its shaded area in fraction and percentage.

WALT: I can state what fraction and percentage of a shape is shaded D. 8/16 = ½ = 50% 11/25 = 44% B. 9/25 = 36% E. 34/63 = 54% C. 14/24 = 58.3%
