I recall a novel where a kid learns psychic powers by squeezing little cubes with binary numbers on them?
Does anyone remember this story from my childhood?

This is Christopher and his Magic Powers by Richard Koff.
Christopher is 13 and often too smart for his own good. He hates school and can’t seem to stay out of trouble. On a dare he knocks on a door to a house all his friends say is haunted and meets a strange, quiet man who calls himself the Headmaster. The Headmaster starts Christopher on a series of lessons unlike anything he was taught in school. He learns how to move objects with his mind alone, how to read other people’s thoughts, he becomes invisible or shrinks to the size of a pencil. It’s not just for fun. The Headmaster has a mission for Christopher that will change his life forever.
Mention is made in this mini-review of the binary blocks
The book is basically about a boy who bravely knocks on the door of a supposedly haunted house, wherein he meets "The Headmaster", a mysterious person who knows an awful lot about Christopher. Over the course of the book, he helps Christopher develop his mental abilities, with the aid of some little gold cubes with binary numbers on them (I still think of this book when I use binary).
