  2. Adding and subtracting fractions 22/05/2014 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.

  3. Must learn: to add and subtract fractions with a common denominator. (5c/E-) INTRODUCTION Colour in the fractions and add them. What do you notice? 5 7 2 5 1 10 9 3 2 6 =

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

  5. + = + - = - 16 2 4 1 7 5 16 1 3 9 1 3 10 21 10 10 21 10 21 5 21 7 = = = 4 + 1 16 - 9 10 21 YOUR TURN (mini whiteboards) 1) 2)

  6. A bit of work… Task 1 – Bronze (L5c) Task 2 – Silver (L5a)

  7. MINI-PLENARY = + 5 1 7 12 6 12 Q1 TRUE FALSE Stand Up Remain Seated

  8. MINI-PLENARY = + 2 4 6 7 7 14 Q2 TRUE FALSE Stand Up Remain Seated

  9. MINI-PLENARY = - 1 7 2 6 18 9 Q3 TRUE FALSE Stand Up Remain Seated

  10. Could learn: to add and subtract fractions with different denominators.(two change) (6c/D-) + Equivalent Multiples of 3 and 4 Equivalent 3 4 6 8 9 12 12 16 15 20 12 is the LCM + =

  11. Multiples of 4 and 5 Multiples of 2 and 3 + = + - = - 11 16 5 4 1 3 2 1 5 1 4 2 3 5 20 20 2 4 20 3 6 5 6 6 8 4 10 6 12 6 15 9 = = 8 16 20 12 10 20 15 25 20 is the LCM 16 - 5 3 + 2 20 6 6 is the LCM YOUR TURN (mini whiteboards) 1) 2)
