Catch Comet

What students practice

Students practice doubling and halving two-digit numbers, answering prompts like double 36 or half of 84 as they appear on screen.

How to play

A comet loops around a track past four numbered rings; players watch for the ring that matches the answer and press the space bar while the comet is inside it, with no need to rush since the comet simply goes around again. Catching the wrong ring freezes the action while the correct answer is shown, and that question returns again later; letting three comets escape ends the mission.

Teacher Setup

Teacher Setup lets a teacher choose the question types, number size, and speed, and turn off the on-screen answer after a miss to make it more of a quiz; the end screen offers a printable student report listing the skills to practice.
