Explanation
Six is five and one more. Seven is six and one more. A ten-frame is a box with ten squares, five in each row. We fill the top row first, then the bottom row. Six counters fill the top row and one square in the bottom row. Seven counters fill the top row and two squares in the bottom row. Write 6 and 7 the way a grown-up shows you, and say each number as you write it.
