Gallery

Map Reading

Students will examine a street map, interpret the street map coordinates, and relate the street map to an x-y coordinate grid.

Burning Candles

Students will explore how the height of a burning candle changes with time. In one case, they will get information by watching a video of candles burning. In another case, they will be given data with which they can calculate a candle's height at any given time.

More Directions

Students are given instructions on what path to take to get to a friend's house. But these instructions are incomplete because a starting point is not given. Their task is to figure out which starting points will make these instructions work.

Leagues

Students will determine how the length of a sports league's playing season is affected by increasing the number of teams from 22 to 30. They will use the number of times a game can be played each week and the present length of the season to solve the problem.

Traffic

Students will figure out the distance between cars on a highway and how many cars there are along a 1-mile stretch of the highway. They will use the speed of the cars and how often a car passes a certain point to solve the problem.

Leaky Faucet

Students will watch a video of a sink filling with water. From that, they will determine how long it will take for the sink to fill up completely.

Frog Jump

Students are shown a drawing of yellow and green frogs arranged in a straight line. The yellow frogs are on the left, and the green frogs are on the right. Their task is to figure out how the yellow and green frogs can switch positions if they can move only by leaping according to certain rules.
