Baby stacker rings. Think of the baby toy, where multi-coloured rings are stacked on a pole. Rather than having the three different graphics - a rainbow for independence, a tower for complexity and a flower for variety - I am experimenting with the same visual, this time as baby stacker rings. My hope is that the hands on manipulation of each of the three trajectories will help students monitor their own learning. Good luck to me, I will let you know how it goes.
