PRESENTATION 2:

1.     Lay out the Ten Board vertically on the left of the mat and say: “This is the Ten Board.”

2.     Read all the numbers on the board: “ten, twenty, thirty, forty… ninety.”

3.     Read the number 10 on the board, then place 1 ten-bar beside it and count it. Pointing to the board and say: “This says 10,” then pointing to the ten-bar and say: “This is 10.”

4.     Read the number 20 on the board, then place 2 ten-bars beside it and count it: “10, 20.” Pointing to the board and say: “This says 20,” then pointing to the ten-bars and say: “This is 20.”

6.     Continue in the same manner until 90.

7.     Go back to the beginning of the board and repeat: “Ten, twenty, thirty, forty… ninety.” Tell the child that the “ty” tells you that there is a ten in a number. “Forty tells us that there are 4 tens.”

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.
