Ratio, Proportion & Rate of Change for Kids
(scroll this section to read all)



Knowing how to work with proportions, ratios and rate of change is a useful skill to have in everyday situations as well as being important in a number of jobs and career situations especially in scientific, mathematic, engineering, business finance and accountancy arenas.

After you have a good understanding of Ratio, Proportions and Rate of Change you should be able to:

  • understand relative quantities and sizes
  • use proportions in real life situations such as recipes
  • work out percentage increases or decreases to a value
  • work out simple financial interest calculations
  • understand and solve problems rates of change e.g. speed

Check out our high quality resource links below which are a tremendous list of games, activities, videos and worksheets which will give you the best possible start in understanding ratios, proportions and rate of change in your quest for math stardom!
