Subtraction with Negative Numbers

Students learn how to subtract with positive and negative numbers on a number line and using written methods.  More able students  substitute negative numbers into simple expressions.

The start of the lesson is used to recap adding with negative numbers.  In the main part students are shown how to perform subtraction with negative using a number line.  This leads on to using written methods to solve harder problems. At the end students try to find two numbers that have a given sum and difference.

Differentiated Learning Objectives
  • All students should be able to use a number line to find the difference between a pair of integers.
  • Most students should be able to use written methods to calculate the difference between positive and negative integers.
  • Some students should be able to subtract with negative integers using written methods.

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 […]
