# Rounding to a Significant Figure

Students learn how to round a number to a significant figure using number lines and place value.  As learning progresses they are challenged to approximate square and cube roots.  An interactive Excel file and Tarsia activity are included in order to provide additional consolidation.
##### Differentiated Learning Objectives
• All students should be able to round a positive number, greater than one to one significant figure.
• Most students should be able to round any number to one or more significant figures.
• Some students should be able to calculate the limits of accuracy when a number has been rounded to a significant figure.

#### 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 […]

#### Arithmetic and Geometric Sequences

Students learn how to generate and describe arithmetic and geometric sequences on a  position-to-term basis.  Learning progresses from plotting and reading coordinates in the first quadrant to describing geometric sequences using the nth term. This unit takes place in Term 4 of Year 10 and is followed by the equations of straight line graphs. Arithmetic […]
