Remember: Read a frame by its rows, tens first. For a nearly full row, look at the gap. An empty row is a zero.
Read and answer
Read the story, then answer.
Pip's gameAt the school fair, Pip runs the Flash Frame game. Pip lifts a cloth for one blink, then drops it. Each player says the number. Counting every bead is too slow. Read the rows: the top row first, then the row below. Three tens and six ones make thirty-six. If a row is nearly full, look at the gap. Eight across leaves a gap of two. An empty row is a zero, but it still holds its place.
