Numbers - Week 36 - Lesson 2 - Order of Operations Cont. (NP)
Starter:
Insert brackets into the following equation to make the biggest answer possible: 50 / 2 - 3 x 4 + 6
- Shows the importance of following the steps to PEMDAS and moving from left to right when solving an equation
Lesson:
- Review steps: PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
- We will begin to work with equations with more operations, building on our knowledge from last class.
- Worksheet to practice with more order of operations
If they can master the following questions:
9 + 2 x 5 - 11
(3 + 4) x (4 - 3)
14 x (15 - 7 + 4)
2 + 9 x 6
18 / (3 x 6 - 9) x 3
3 + 4 x 4 - 3
Then you can do harder questions, for example:
7. 16 / 8 + 2 x 5 - 21 / 7
8. (18 / 3 + 28 / 4 + 2 x 4) / 3
9. 2 + 15 / 3 - 2 x 3 + 10
10. 3 x (24 / 2 - 3 x 4 + 2 x 6)Various Difficult Order of Operation Problems
