Master enlarging and reducing shapes with scale factors! Identify scale factors, calculate new dimensions, and draw scaled shapes on the grid.
Practice working with scale factors on a coordinate grid. Identify scale factors, calculate scaled dimensions, and draw enlarged or reduced shapes yourself!
Compare an original shape with its enlargement or reduction to work out the scale factor.
Given a scale factor, calculate the new width, height, or perimeter of a shape.
Click grid intersections to plot a shape that's been enlarged or reduced by a given factor.
Practice with whole number scale factors, then progress to halves, quarters, and other decimals.
Choose which scale factor skills to practise, your difficulty level, and which shape types you'd like to see.
Depending on the question type, you'll compare two shapes, calculate a new dimension, or draw a scaled shape.
Type your answer, or click grid points to plot your shape. Close a drawn shape by clicking back on your starting point.
