# Rounding Decimal Numbers

Students learn about accuracy when rounding decimal numbers.  Learning progresses from rounding to one decimal place using a number line to any decimal place using written methods.  More able students consider the limits of accuracy when a number has been rounded.

At the start of the lesson students recap addition and subtraction with decimals.  In the main they learn how to round any number to a given decimal place.  The plenary is used to assess the progress made against the differentiated learning objectives.

##### Differentiated Learning Objectives
• All students should be able to round a number to the first decimal place.
• Most students should be able to round a number to any given decimal place.
• Some students should be able to determine the upper and lower bound when a number has been rounded to a decimal place.

#### 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 […]
