Rounding Numbers to a Significant Figure

Students are introduced to rounding numbers to a significant figure.  Learning progresses from rounding whole numbers from one significant figure to rounding decimals to two or more significant figures.  More able students are challenged to find the limits of accuracy for rounded numbers.
Differentiated Learning Objectives
  • All students should be able to round an integer to the first significant figure.
  • Most students should be able to round a number to a given significant figure.
  • Some students should be able to determine the limits of accuracy for a number 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 […]
