Copy the Rhythm
Tap the drum as many times as you hear, copy long and short beats, then make a rhythm of your own.
Telling Sounds Apart
Listen to a sound to find the matching picture, and compare loudness and speed by watching the waves.
Speed, Distance and Time
Drive a car to work out speed = distance ÷ time, then send it back to see how distance travelled differs from displacement.
Beats and Note Values
Balance notes, fill a measure in 4/4, and change the tempo to hear how long each beat really lasts.
Order of the Day
Read the sun's position and sky color to tell morning, day, evening, and night apart, then put the day in order.
Sleep and Health
Sleep hours shift one square at a time, showing how much sleep is just right and how sleep debt piles up.
Classroom Timer
Watch the circle shrink as the activity time counts down, and run several turns back to back.
Asynchronous Code
Set timer delays and see why code doesn't run in the order you wrote it, and why loops need a stop condition.
Speed
Change distance and time to work out speed, then race two objects side by side to see which is faster.
Elapsed Time
Move the hands of two analog clocks to see how start time plus elapsed time gives the end time, then test it in a quiz.
