||4 – 5 years approx.
Leave the card in place and continue with 12.
Point to the next number 10 on the board and ask the child if he remembers what that number is.
The child should respond with, “ten” in which case you continue the lesson.
Show the child how to take the loose “two” number card and how to slide it into the right hand side of the board covering the 0 so that the number now formed is 12 which is directly below the 11.
Remind the child that when we added two to the ten (as we did with the beads) we make a new number called twelve. This is how we would write 12.
Repeat this with 13.
In the SECOND PERIOD repeatedly ask the child to show you the various amounts 11, 12 and 13.
In the THIRD PERIOD, try to isolate each amount by covering each top number formed with a small piece of felt. Asking the child (in order) “what number is this?”
Consolidate by asking the child again to tell you the name of all three numbers.
The next time you work with this, do one known and two unknown numbers.
End the work cycle.
