[] Car Race Animated Activity

[]Wind and River Current Problem Solving

[]User speed and position of cars in a race to understand slope and intercept.

[]Examines the idea of wind and river current adding and subtracting from the speed of plane or boat.

[]6 (or any time after the idea of linear equations - does NOT require explanation of slope and intercept)

[]8 (good problem for beginning systems of equations 2x2)

[]This activity is suitable for younger children - just change the questions!

[]Images are terrible - looking for new ones :)
