After a couple videos it was easy to learn to be able to teach.My daughter’s favorite was the division board. It was easy to turn into a fun game of customers coming into a shop to buy ice cream and splitting them amongst them. Within a month of every day use she fully grasps the concept of division and now does it in her head.These boards have aided in her confidence.They’re made of wood and solid. We haven’t lost a single bead but there’s been many close calls.I used this board for my daughter, 5, and to help my nephew 9, and niece 10 who were struggling with the visualization of multiplication and division. These boards helped them to see how it works.
