Design the Mascot
Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.
Balanced Assessment
Oil Consumption
An assessment presents a chart displaying oil consumption Pupils use the chart to determine the greatest increase in consumption, and then apply that information to figure out when the consumption may reach 100 million barrels a day.

Explora-Pond: Surface Area
Learners estimate the surface area of a pond using ratios and chance methods of estimation. They gain insight into how well estimations based on chance outcomes match the average of a maximum area estimation and a minimum area estimation.

Circle Up Your M&Ms
Fifth graders estimate how many M&Ms are in a pre-counted bag. They determine how many colored M&Ms are in a bag, then decide which of the two, bar graph or circle graph (in this case, circle graph) would be best to show te results.

Estimating Percentages
In this estimating percentages worksheet, students read a problem that gives the percentage of a dollar amount, for example; 8.6% of $75.09 = $5.46. They estimate to determine if they believe the problem is "definitely wrong" or...
