Making Approximations using Rounding

Students learn how make approximations by rounding numbers to one significant figure.  As learning progresses more able students learn how to estimate the solution to problems involving square and cube roots.
Differentiated Learning Objectives
  • All students should be able to approximate a product by rounding each number to 1 significant figure.
  • Most students should be able to make and justify approximations by rounding to a significant figure.
  • Some students should be able to make and justify approximations of square and cube roots.

Calculating Instantaneous Rates of Change

When calculating instantaneous rates of change students need to  visualise the properties of the gradient for a straight line graph.   I use the starter activity to see if they can match four graphs with their corresponding equations. The only clue is the direction and steepness of the red lines in relation to the blue line […]

Converting Between Fractions, Decimals and Percentages

Fractions, decimals and percentages are ways of showing a proportion of something.  Any fraction can be written as a decimal, and any decimal can be written as a percentage.  In this blog I discuss how to use the place value table and equivalent fractions to illustrate how fractions, decimals and percentages are connected. You can […]

Comparing Datasets using the Mean and Range

In my experience, students, in general, find the concept of a mean straightforward to calculate and understand. However, the mean alone does not provide a complete picture of a set of data. To achieve this, a measure of spread is also required. The range is the simplest measure that can be used for this. Not […]
