# 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.

#### 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 […]
