Count what you see, then tap the number.
Number Crunch shows a group of objects and asks how many there are. It is the bridge between saying number words out loud and recognising written numerals: the child has to count a real set, then pick the digit that matches. The picture set changes between rounds so the counting stays about the quantity rather than a memorised image.
The 2-4 level counts sets of up to five objects and asks which of two small groups has more. Objects are drawn large and laid out three to a row, which keeps them countable by pointing rather than by scanning.
