Year 6 ratio Ratio is now a category all of its own in Year 6 but it is important to approach this topic with care as explanations need to be clear. Children should be familiar with the following vocabulary: In every,  for every. Children should be able to handle problems involving simple ratio and proportion and know that 2 in every 5 means 4 in every 10 etc. They should be able to construct simple patterns in which, for example, every fourth square is coloured. A good introduction to ratio is to use a ‘feely bag’ with a number of cubes in it ,having two different colours. Children take out one cube at a time, up to a total of about 10. They record the ratio of the cubes taken out e.g.             red:blue    3:7 Before taking any out try to predict the outcome. Change the number of one colour of cubes etc. We have increased our selection of ratio worksheets, recently including two new ones on equivalent ratios. An understanding that  1: 6 is equivalent to 2:12, 3:18 etc is needed for these pages. Go to Year 6 ratio
