Research and fi nd at least 10 facts or rates in your community that you can
compare from last year to this year. Some examples might include amount of
rainfall, number of students passing the state test, number of students on
the track team or number of policemen at the local station.
Find the percent increase or decrease for each quantity or rate from last year to
this year. Record whether it is a percent increase or a percent decrease.
Organize the information in a chart to include the quantities or rates from last year as well as this year,
the percent increase or decrease and whether or not it was an increase or a decrease. Finally, predict
what will happen next year if the percent change remains the same. Include this in the chart.
