TASK 1 (GRADE F) EXTENSION 1 (GRADE E) (a) x + 6 = 10 x = 4 1) Here are three equations. (a) x + 6 = 12 Only one with even numbers (b) x – 1 = 5 Only one with minus sign (c) x + 5 = 9 Only one with answer not 6 Give a reason why each one could be the odd one out. (b) w – 5 = 9 w = 14 (c) y + 3 = 8 y=5 (d) p – 9 = 1 p = 10 x=5 (e) 2x = 10 (f) 3x = 18 z (g) =8 3 (h) 4x = 10 q (i) =1 4 (j) x + 9 = 10 x=6 z = 24 x = 2.5 q=4 x=1 (k) r – 7 = 21 r = 28 s s = 12 (l) =2 6 2) Set up an equation to represent the following. Use x for the variable. My sister is 3 years older than I am. She is 17 years old. How old am I? x + 3 = 17 x = 14 3) Set up an equation to represent the following. Use y for the variable.

PLT Skills SOLVING EQUATIONS EXTENSION 3 (GRADE D) TASK 3 (GRADE E & D) (a) + 7 = 15 x = 24 1) A teacher read out the following to her class: “I am thinking of a number. I subtract 5 from it and then (b) +3=5 t = 10 (c) –5=2 w = 21 (d) + 3 = 12 x = 72 divide the result by 4. The answer is 7. What number did I think of to start with?” (a) What was the number the teacher thought of? 33 (b) Bryn misunderstood the instructions and got the operations the wrong way round. What number did Bryn (e) –3=5 (f) =3 k=5 (g) =3 h = 28 m = 56 think the teacher started with? 48 2) At a conference, doughnuts are delivered for the mid-morning break. The waiter takes five off the tray before taking them to the delegates. There are (h) =1 w=5 (i) = 10 x = 35 (j) =5 y = 33 10 delegates and they each get two doughnuts.

Draw your brain In your brain, write or draw everything you can remember about solving one and two step equations. 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?
