Objective: I should be able to add and subtract fractions. (L5-6/Grades E-D)
Keywords: numerator, denominator, simplify, equivalent
By the end of the lesson:
Must learn: to add and subtract fractions with a common denominator. (5c/E-)
Should learn: to add and subtract fractions with different denominators. (one change) (5a/E+)
Could learn: to add and subtract fractions with different denominators.(two change) (6c/D-)
Real life link: You might need to add or subtract distances involving fractions.

INTRODUCTION
Colour in the fractions and add them. What do you notice? 6 5 9 7 3 2 10 5 2 1 = 3

4. Fractions with different denominators
Should learn: to add and subtract fractions with different denominators. (one change) (5a/E+)
Fractions with different denominators 1 2 4 8 3 8 7 8 3 8 + + =
Can you work out what has happened to get to this answer? 1 3 7 12 4 12 7 12 11 12 + + =
