Combination of 10-90 With Golden Beads and Tens Boards

COMBINATION OF 10 – 90 WITH GOLDEN BEADS AND TENS BOARDS

Purpose:
To teach the names ‘twenty, ‘thirty’, etc. and to associate the name with the quantity and the numeral.
Preparation for skip counting.

Materials:
Two boards with the numerals 10, 20, to 90 printed on them.
A box of forty-five ten bead bars. – A floor mat.

Control:
The teacher and the child as he balances the quantity with the written symbol.

Age:
4 – 5 years

Presentation:

Invite the child to place the boards in order on the floor and to place the box with the bead bars to the left of the board.
Ask the child to read the numerals on the board beginning with ’10’.
Show him how to place one ten bead bar immediately to the left of the numeral.
Ask him to read the next numeral.
He will probably say ‘two tens’.
Say, “Yes, you are quite right but remember it has a special name – it is ‘twenty’.”
“Can you say ‘twenty’?”
“Now we are going to make ‘twenty’ with the ten bead bars.”
“How many will we need?”
“Yes, two.”
“Two tens make ‘twenty’.”
Proceed in this way saying, “This is how we write thirty.”
“Can you make thirty for me?”

Exercise: 

The child works with 10, 20, 30 and may continue to 40, 50, 60 and then 70, 80, 90 with the teacher naming the new names forty, fifty, sixty, etc. for the numerals.
When he has reached ’90’ he will see very clearly how the ‘tens’ have grown from ‘one ten’ to ‘nine tens’ (90) and, as in the previous exercise, he can also see and associate the correct name with the numeral and the quantity.
