Max's little sisters and the Innu girls worked remarkably well together, and all four were years ahead of the standard development that you would expect of a human their age. None were old enough for standard schooling, by human estimations, but they all understood the concepts of holographic design, and with the innate talents of the Innu, they didn't even have any troubles with programming locations for the objects that they wanted to place in the simulation.
They had chosen to work together while taking notes on the changes they needed to make. But because this was a full-on science lesson, according to the Innu mothers, they wouldn't just be placing basic objects. They each needed to modify one they placed and show their work, so their understanding of the principles behind holographic projections could be tested.
