Lesson Plans
• Distance, Speed and Time Relationships #1
Students will examine and compare time versus distance relationships, and represent change over time as seen using a single runner along a line and review results plotted along a graph. This activity helps students identify, describe and compare situations with constant or varying rates of change.
• Interactive Pan Balance
Students can use this interactive pan balance to help understand that equality is a relationship, not an operation.
• The Next Billion
In 1999 the world population passed the 6 billion mark. In this lesson, students predict when it will reach 7 billion. To do so, they use an online counter that simulates the changing world population. They time the counter to find how long it takes for the population to increase by, say, 50 or 100 people. They use that measurement to predict how long it would take for the population to increase by 1 billion. Students discuss the reliability of their predictions, compare them to past trends, and discuss social factors that can affect population growth.
