Little-N has worked with the stamp game and small bead frame for years and can already work out long addition and subtraction sums without using materials. Recently I've been preparing him for multiplication on the small and large bead frame. To prepare him he has revised the following activities.
Long addition and subtraction using the stamp game.
Long addition and subtraction using the small bead frame.
Addition and subtractions with millions using the large bead frame.
Little-N worked on these activities well, soon I will be introducing him to multiplication with the bead frames and checker board.
