Show progress bar to 6-11 year-old kids.
 

Hi everyone!

I want to show some 6-11 year-old kids which progress we made in the last months. I want all of them to understand it, but I don't know how to make my progress bars visual.

I know that it's only when they reach 11 years that they learn ratios and proportional relationships (like 20% or 20/100) in school. So, what way is there for visualizing quantities for the younger ones?

Thank you in advance! :D
