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 8-10 level counts to twenty, adds skip counting in 10s, and includes flash rounds where the group appears only briefly, so the child has to estimate or subitise rather than count one at a time.
