Order of Operations (BIDMAS): Order of Operations (BIDMAS): Inserting brackets Inserting brackets Silent Teacher Intelligent Practice Your Turn Narration Insert brackets to make these calculations true: 8 + 4 x 5 2 = 20 8 + 4 x 5 2 = 58 Practice 8 + 4 x 5 2 = 26
Worked Example Your Turn Insert brackets to make this true Insert brackets to make this true 8 + 4 x 5 2 = 20 7 + 3 x 5 1 = 49 8 + 4 x 5 2 = 58 7 + 3 x 5 1 = 40 8 + 4 x 5 2 = 26 7 + 3 x 5 1 = 19 8 + 4 x 5 2 = 36 7 + 3 x 5 1 = 21
Worked Example Your Turn Insert brackets to make these true Insert brackets to make these true 8 + 4 x (5 2) = 20 (7 + 3) x 5 1 = 49 (8 + 4) x 5 2 = 58 (7 + 3) x (5 1) = 40 8 + (4 x 5) 2 = 26 7 + 3 x (5 1) = 19 (8 + 4) x (5 2) = 36 7 + (3 x 5) 1 = 21
Insert brackets here to make the calculation true: 1) 5 + 4 2 = 13 2) 5 + 4 3 = 22 3) 5 + 4 3 = 27 4) 5 + 4 32= 81 5) 5 + 4 32= 41 6) 5 + 4 32= 149 7) 5 + 4 32 2 = 147 8) 5 + 4 32 2 = 63 9) 5 4 + 32 2 = 19 10) 5 4 + 32 2 = 20
Insert brackets here to make the calculation true: 1) 5 + (4 2) = 13 2) 5 + (4 3) = 17 3) (5 + 4) 3 = 27 4) (5 + 4) 32= 81 5) 5 + (4 32) = 41 6) 5 + (4 3)2= 149 7) 5 + (4 32) 2 = 147 (5 + 4) (32 2) = 63 8) 9) 5 4 + (32 2) = 19 10) (5 4 + 32) 2 = 20
