For Teachers

In this question, you can click on the first part of the question for the visualization to appear. You should see 5 basketball, 25 softball and 125 table tennis balls.

The equivalent is shown via the same height of the drawing. This helps to establish the first part of the question.

The second part has the visualization hint which can be shown on click, you should see 2 basketball and 10 softballs arranged from bottom to top, leaving the top RED color as the maximum number of table tennis balls you can add to the container.

Students can drag to recentre and mouse scroll to zoom in, phone will be pinch in and out.

Finally, there is a check answer input field for testing your own understanding.

The variables can be changed to a different context for stronger concept building.

Enjoy!
