    "Danielson's book reveals the wonder and freedom of expression that many children don't often experience in mathematics. A single, simple question puts children in a position to speak mathematically, even at early ages. Ask students of all ages, 'Which one doesn't belong?' and revel in the reasoning and conversation that results."

    - Dan Meyer
