# Substituting Numbers into Formulae

Students learn about substituting numbers into formulae using the order of operations.  As learning progresses students are challened to substitute decimal and negative numbers into increasingly complex formulae.

The start of the lesson recaps using the order of operations to arrange a series of calculations in ascending order.  The plenary challenges students to apply substituting numbers into formulae in a real life context.

##### Differentiated Learning Objectives
• All students should be able to substitute integer values into a formula.
• Most students should be able to substitute integer and decimal values into a formula.
• Some students should be able to substitute known values into a formula.

#### Surface Area of Cylinders

When I teach how to find the surface area of cylinders I like to add a constant level of challenge and enjoyment to the lesson.  Rather than repetitively calculating the surface area of a cylinder I introduce more complex cylindrical shapes.

#### Teaching Mathematics for a Growth Mindset

Inspiring students to enjoy maths and feel the success that comes with attempting a difficult challenge is why I teach.  The feeling of success is addictive.  The more students experience it the more they want it and the further out of their comfort zone they are willing to go to get more of it.  Teaching […]

#### Equation of Straight Line Graphs

To find the equation of straight line graphs students need to calculate the gradient using two pairs of coordinates and the intercept which is the y value of where it crosses the vertical axis.  Examiner’s reports of past exam questions show students are more able to find the intercept of a straight line than they […]
