Five LEGO WeDo 2.0 Math Challenges
- The bee rotates more during the first second of a program than it does during each subsequent second. Expressed as a decimal, how many revolutions does the bee make in 1 second at a speed of 1? ____ How many revolutions does the bee make in 11 second at this speed? ______
About how many revolutions should the bee make during 7 seconds at a speed of 1?_____
- Create an angle maker with 6 gears (3 gear connections). Record the ratio between of the number of teeth of the driving gear to the driven gear in each connection: ____:____; ____:____; ____:____
If you turn your handle clockwise 17 times, what will be the measure of the angle created? ___
3.Have the mantis sit up as erect as possible, with its legs fully extended straight downward. Measure the height (distance from the surface on which the mantis is sitting), in cm, of the lower tip of its “hands” when its “arms” when pulled all the way back _____. Measure the height, in cm, of the tip of its “hands” when its “arms” are fully extended _____. How much longer are the fully extended arms compared to the pulled back arms? _____ The mantis will be pushing dice up the slope of a partially open 1½ inch three ring binder, with one of the binder covers laying flat on the surface. Measure, in cm, the width of the spine of the binder ______and the width of the cover of the binder _____. You will keep the binder open by supporting the high end of the slope with a tower of LEGO bricks. How many cm tall is one brick ____?
In order for he mantis to successfully push dice up the slope, how many bricks high will your LEGO tower need to be?______
4.How many inches does frog travel in 3 seconds at a speed of 8? ______How many inches does tadpole travel in 3 seconds at this speed? ______
If you put frog and tadpole 15 feet apart and then they begin walking toward each other at a speed of 8, how long will it take until they meet? _____How far will frog travel until they meet? _____ How far will tadpole travel? _____
5.Time how long it takes steer car to travel 10 feet at a speed of 8_____. Time how long it takes steer car to make a full (360 degree) turn at this speed. Create a program for the car to travel at this speed around a counterclockwise path consisting of the perimeter of a square whose sides are each 1 yard in length. Keep in mind that during each turn the car backtracks from the vertex about 9 inches in each direction.
