If I was still an early childhood teacher, I think I would use these big dice for all sorts of things in my classroom. I would have the kids roll them to take turns, make decisions, and choose activities.
Even very young children could roll one of these die and, with help, count the pips to find out what number it is. If you have three children in your group, each one could roll the die, tell their number, and put themselves in order based on that number. Here is a nice lesson plan that uses dice for counting.
These dice are a bit different. Rather than pips, they have the number written on each side. These too are interesting- especially if children are working on identifying integers rather than counting.
Different materials support different learning goals and create different learning outcomes. Yeah for dice!
