For 7th graders, no other concept gets as much “bang for your buck” as proportions. We have started a list of problems that can be solved with a proportion and it continues to grow each day.
Here is what we have so far:
· Word problems with three numbers
· Scale drawings and maps
· Unit Rates
· Converting measurements
· Two equivalent fractions with one number missing
· Similar figures
· Shadow problems
· Taxes, tips, discounts
· Probability predictions
When in doubt, proportion it out – especially if you have three numbers! Below are some examples of proportion problems we have worked on so far.
