ABCya! How Many Marbles?

How Many Marbles is a fun 3D activity for children to practice estimating.

Rotate the jar to see the number of marbles from different sides. Estimate the number of marbles by using the arrow keys to answer. How close can you get? This activity requires WebGL. We recommend up-to-date operating systems and browsers. Google Chrome works best.
