3.     Add another unit bead and place all three next to Tile 3 and say: “3.” Continue up to “9”.

4.     Add another unit bead, but say: “10 units are the same as one ten.” And exchange them for a ten-bar.

5.     Place the ten-bar to the right of the top “10” section on the board and say: “Ten.”

ADDITIONAL INFORMATION:

Although this activity is recommended for children 4.5 years and up, J tried this only for the first time today at 5+ years old (5Y4M7D). We recorded the videos below for memory. He could say the numbers in Chinese very well now, but we are still practicing saying the numbers in English and Danish.
