## Exercise 1

MATERIAL:

• 1 set of the colored bead bars
• 9 ten bars
• A green table mat

PURPOSE:

To teach the names 10 to 19 in association with the quantities

AGE:

4 years and older

EXERCISE:

The names are taught using the three period lesson.  The teacher takes three ten bars and the colored "1" bead bar, the colored "2" bead bar, the colored "3" bar and a mat to the child's table.  She sits beside the child.  She spreads the mat on the table and puts the bars to one side.

Period 1

She places a ten bar in front of the child and asks how much it is.  He can tell her it is "10."

She places the colored "1" bead bar to the right of the ten bar, and says, "10 and 1 are called eleven.  Eleven."  She repeats the name several more times.

The teacher puts the ten bar and the "1" bar to one side and places another ten bar in front of the child.  To the right of it she places the colored "2" bead bar.  She says, "10 and 2 are called twelve."  She repeats the name several times.

The teacher puts the ten bar and the "2" aside and places another ten bar in front of the child.
To the right of it she places the colored "3" bead bar.  She says, "10 and 3 are called thirteen."  This stage is repeated as often as is necessary for the child who is being taught.

Period 2

The teacher puts the three quantities in front of the child and asks him for various ones.  "Show me eleven."  "Which is twelve?"   "Point to thirteen," etc.  This is repeated as often as necessary for the child being taught.

Period 3

The teacher puts one quantity at a time in front of the child and asks him to name it.  When he does, she suggests he count the beads.  The teacher points (using a pencil) to each bead in turn while the child counts.  This is repeated as often as necessary for the child being taught.

Summary

The quantities are arranged in a column one below the other and named.

On subsequent days, the quantities already taught are taken, and then one or two more added in sequence until the child knows them all.  The material is available in the classroom where the child can help himself to it and make the quantities 10 to 19 as often as he likes.
