This lesson we will repeat:

- Making a formula for a story
- Solving an equation for a story
- Making a formula for a graph
- Solving an equation for a graph
- Solving a given equation

We will pay extra attention to:

- Correct notation of your calculations (exercise 39)
- Solving a set of simultaneous equations (exercise 43)
 

Tactical thinking

Today we will take a critical look at the Mixed Exercises.
What should you be able to do?
What strategy will you use?
Do you recognise exercises you have made before?
What type of question do you see a lot?
What do you find easy?
What do you find difficult?

I have to make a formula at exercises:

At these exercises I have to make and solve an equation:

Making a formula

Which steps do you follow? Look these up if needed and write them down in your notebook.

The following questions will help you determine if you are capable of making formulas.

What is the formula at exercise 36a?

What is the formula at exercise 38a?

Which two formulas correspond to the graphs at exercise 40a?

Making equations

How do you make an equation from a formula?

The following questions will help you determine if you are capable of making equations.

What equation should you make at exercise 36b?

What equation should you make at exercise 38b?

Which equations should you make at exercise 40b?

Solving equations

Work in pairs to solve the 4 equations from
exercises 36, 38 and 40

Discuss in pairs:
- Which steps should you write down?
- What is the correct solution?

Practicing correct notation

Make exercise 39 in pairs.
What do you have to write down? What do you not write down?

Your teacher will discuss the exercise on the board.

Who can solve this problem?

And who can solve this one?
