Fifth Grade
In fifth grade, Yohai chose "The Big Cats" as an individual project. He read many books in English on cats, including stories. He also read science fiction, and enjoyed especially the ones where "you pick the next move." He continued studying piano and decided to take private lessons in mathematics. He loved geometry in particular. He liked swimming and long walks, and computer games.

The Hebrew site shows his work on the big cats, a flowchart he drew, a game of snakes and ladders with questions on school subjects. He still loved to draw turtles and cats.
