Learning the signs is one thing. Reading them fluently is the real challenge.
Practice reading ASL number handshapes through Sudoku
Recognizing ASL number handshapes takes practice. Sudoku gives you 118 puzzles worth of it.
This Sudoku workbook uses American Sign Language number handshapes instead of printed digits. Every puzzle gives you repeated, low-pressure practice recognizing the ASL handshapes for numbers 1 through 9 while you solve a familiar logic game.
Unlike flashcards or charts, Sudoku requires you to actively reason about each handshape: which one is missing, which one belongs in this cell, does this row already have it. That active engagement builds the kind of recognition that transfers to real conversation.
No signing partner needed.
Viewer's Perspective - Why It Matters
Sign language illustrations are often shown from the side or at angles that make it easier to understand how to form the handshape. That helps when learning to sign. But when learning to read someone else's signing, you need to recognize handshapes the way you actually see them, from the front, facing you. This book shows all handshapes consistently from the viewer's perspective, optimized for recognition rather than production.
The illustrations are from a custom professional ASL sign language font built specifically for Project FingerAlphabet, validated by several independent, recognized sign language experts, including an expert from Gallaudet University.

Each puzzle fills two-thirds of an 8.5 x 11 inch page in 30-point print, with space for your annotations.
