2. Sort them out in group from right to left the unit beads in a bowl, ten-bars, hundred-squares and thousand-cubes on the mat.
3. Ask your child to count the unit beads into an empty bowl and when he reaches the tenth unit, let your child exchange them for a ten-bar, say, “Exchange!” and place it with the other ten-bars.
4. Repeat in the same manner until there are insufficient units to exchange a ten-bar.
