Enlarging Shapes on a Grid

Students learn how to enlarge shapes objects on a grid using a centre and scale factor. Learning progresses from enlarging shapes to a positive scale factor to fractional scale factors. More able students are challenged to describe as well as perform enlargements by finding the centre and scale factor.The start of the lesson recaps describing translations using vectors. At the end of the lesson students are challenged to perform and describe enlargements on an isometric grid.
Differentiated Learning Objectives
  • All students should be able to enlarge an object using a positive integer scale factor and centre.
  • Most students should be able to perform and describe an enlargement to a positive integer scale factor and centre.
  • Some students should be able to perform and describe an enlargement to a positive fraction scale factor and centre.

Solving Two Step Equations using the Balance Method

An equation is when one expression, or term, is equal to another.  To solve an equation means to find the value of the variable (represented by a letter) that makes the two expressions equal.  There are two types of equations for secondary school mathematics, linear and none-linear.  In this blog I write about how I […]

How to Simplify Surds

When learning how to simplify surds students need to understand the difference between a rational and irrational number. Rational numbers include integers and terminating and repeating decimals. They can be written as a fraction with both the numerator and denominator as integers. An irrational number is a number which, in its decimal form does not […]

Sharing an Amount to a Given Ratio

There are three common methods for sharing an amount to a given ratio.  Depending on the age group and ability range I am teaching I would choose one approach over the other two. The three methods are: Using fractions Unitary method Using a table In this blog I will demonstrate each of the three methods […]
