Does anyone else still struggle to help their littlest people with b and d? I was pretty sure I had seen all the tricks of the trade until this last year when I thought I invented a new one. Come to find out it wasn't so new, and I still wonder how in the world I just came to know about it 22 years into my career, but it really makes a ton of sense. Maybe there's someone else out there who hadn't seen this either. Anyway, I realized that you can make a lowercase b and d on each hand as a way to check on directionality. Since b comes before d in the alphabet, the kids could tell that b is on their left hand and d is on the right. The best part of this trick is that the visual is mobile. It travels with them wherever they go. They don't need to look anywhere but on their hands. Brilliant!
