  1. Targeting Grade C Starter - Tarsia

  2. What can we do to start – try 5 What’s your level (1 – 10) 3x – 5 = 10 5y + 6 = 21 2(x + 4) = 12 5(y – 3) = 5 8x + 12 = 20 4x +5 = 2x + 9 3y – 2 = 2y + 8 5t – 8 = t + 16 15x + 6 = 7x - 2 20y – 16 = 18y -10

  3. E/D Solve the following (i) x + 5 = 16 (ii) 3x + 4 = 19 (b) 6y + 9 = 45 • D/C • Multiply out the brackets first: • 2(x + 3) = 16 • (b) 3(2x – 3) = 9 C (i) 9x – 14 = 4x + 11 (ii) 20y – 16 = 18y - 10

  5. Where did you finish? – try 5 What’s your level now? x = 3 3x – 5 = 10 y = 3 5y + 6 = 21 2(x + 4) = 12 x = 2 5(y – 3) = 5 y = 4 x = 1 8x + 12 = 20 4x +5 = 2x + 9 x = 2 3y – 2 = 2y + 8 y = 10 5t – 8 = t + 16 t = 6 15x + 6 = 7x - 2 x = -1 20y – 16 = 18y -10 y = 3

  6. 4. The perimeter of this triangle is 19 cm. All lengths on the diagram are in centimetres.Work out the value of t. t = …………………………… (Total 3 marks) Are you ready for the answers ? 4⅓ 3t + 6 = 19 3t = 13 t = 13/3 = 4⅓ Lesson

  7. Factorising Brackets • What do we know?

  8. Are you ready for the answers ? 3(3x + 4) 2(x -3) Can you factorise these? Write down your solutions to: 1. 9x + 12 2. 10x - 6 • 9 – 3x • 3x + 5xy • x² - 9x • x² + x • 3x² + 6xy • p² + 6p • 8x² + 4x • ax² + ax (10) 3(3 – x) x(3 + 5y) x(x – 3) x(x + 1) 3x(x + 2y) p(p + 6) 4x(2x + x) ax(x + 1)
