TASK 1) 2) Factorise: 64 8et + 12t = 8 and -8 = 4t(2e + 3) 5) Find the LCM of 4 and 6 3) Expand: -6(3x - 5) = -18x + 30 6) Find the HCF of 21 and 35 =7 = 12 EXTENSION Expand and simplify: x x (x + 7)(x + 9) = x2 + 63 + 7x + 9x = x2 + 16x+ 63 x x 4 4) g divided by g = g-5 7) Write 42 as a product of prime factors = 2x3x7 9 Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager Team Worker PLT Skills Nth term from picture patterns Which ones are you using? EXAMPLES 1) The diagram shows a pattern of matches building up. 7 4 +3 squares building up. 13 10 +3 2) The diagram shows a pattern of +3 (a) Work out the nth term for the pattern of matches 3n + 1 (b) How many matches will the 100th pattern have? Substitute 100 into the nth term above 3 x 100 + 1 = 301 3 5 7 +2 +2 (a) How many squares will there be in the nth pattern? 2n + 1 (b) What is the largest pattern number you can make with 187 squares? Make the nth term equal to 187 and solve 2n + 1 = 187 -1 2n ÷2 n -1 = 186 ÷2 = 93 Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager Team Worker PLT Skills Nth term from picture patterns Which ones are you using? TASK (GRADE C) 1) A pattern of squares is built up from matchsticks as shown. 2) A pattern of triangles is built up from matchsticks. Appropriate diagram (a) Draw the fifth set of triangles in this pattern. (b) How many matchsticks are needed for the nth (a) Draw the fourth diagram. Appropriate diagram 2n + 1 (b) How many squares are there in the nth diagram?4n - 3 set of triangles? (c) How many squares are there in the 25th diagram? 97 (c) How many matchsticks are needed to make the 60th set of triangles? 121 (d) With 200 squares, which is the biggest diagram that (d) If there are only 100 matchsticks, which is the could be made? 50th largest set of triangles that could be made? 49th 3) A conference centre had tables each of which could sit 4)Regular pentagons of side length 1 cm are joined six people. When put together, the tables could seat people as shown. together to make a pattern as shown. Copy this pattern and write down the perimeter of each shape. (a) How many people could be seated at four tables? 18 (b) How many people could be seated at n tables put together in this way? 4n + 2 (c) At a conference, 50 people wished to use the tables in this way. How many tables would they need? 12 (a) What is the perimeter of patterns like this made from (i) 6 pentagons (ii) n pentagons (iii) 50 pentagons? 20cm (3n+2)cm 152cm (b) What is the largest number of pentagons that can be put together like this to have a perimeter less than 1000 cm? 332 Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager Team Worker PLT Skills Nth term from picture patterns Which ones are you using? EXTENSION (GRADE C) n Picking a large value of n gives an answer of zero on a calculator, so eventually the whole area will be covered. Creative Thinker Effective Participator Independent Enquirer Reflective Learner Self Manager Team Worker PLT Skills Nth term from picture patterns Which ones are you using? MINI-PLENARY A pattern is formed from squares. 1 5 3 (a) Draw Pattern 4. (1 mark) 7 (b) Find the number of squares in Pattern 6.

LINK BACK TO OBJECTIVES - Accurately find the nth term of a sequence from picture patterns. What grade are we working at? PLENARY ACTIVITY GCSE GRADE C EXAM QUESTION Consecutive patterns are put together. (a) The numbers of counters in the combined patterns form the sequence: 4, 9, 16, … How many counters will be in the next combined pattern in the sequence? 25 (b) What type of numbers are 4, 9, 16, … ? Square numbers (c) How many counters will be in the combined pattern formed by patterns 9 and 10? 10 x 10 100 What have you learnt? Draw your brain In your brain, write or draw everything you can remember about finding the nth term of a sequence from picture patterns. It can be a skill or a reflection, or something else that might be prominent in your brain. Where are we in our journey? What grade are we working at?
