Mastering Equation Rearrangement: GCSE Maths Lesson

Mastering Equation Rearrangement: GCSE Maths Lesson

Learning Objective

At the end of the lesson, you will be able to rearrange equations confidently, specifically in the context of science formulas.

What do you already know about rearranging equations?

Understanding Equations

Equations are mathematical expressions that show the relationship between two or more variables. They are commonly used in science to express various formulas.

Rearranging Equations

Rearranging equations involves isolating a specific variable to solve for it. It is a fundamental skill in mathematics and science.

Example 1: Rearranging the Speed Equation

Given the formula speed = distance / time, let's rearrange it to solve for distance when speed and time are known.

Example 2: Rearranging the Density Formula

The formula for density is density = mass / volume. We will rearrange this formula to find the mass when density and volume are given.

Practice 1

Solve for the unknown variable in the given equations: a) force = mass × acceleration, b) pressure = force / area.

Practice 2

Rearrange the equations to solve for the specified variable: a) volume = area × height, b) power = work / time.

Checking Answers

Review the practice questions together, ensuring that each step of rearrangement is understood and correctly applied.

Key Takeaways

Rearranging equations is a valuable skill for solving scientific problems and understanding the relationships between variables in formulas.

Worksheet

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
