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 add another ten-bar and place both beside number 20 and count ten-bars: “10, 20.” Pointing to the board and say: “This says 20,” then pointing to the ten-bars and say: “This is 20.”
