Ten sandpaper numerals 0-9 mounted on green board and presented in a wooden box.To teach the child the written symbol for numbers 1 – 10.

The numbers from one to ten in sandpaper mounted on green card.

### MONTESSORI OBJECTIVES:

To teach the child the numerals from one to ten.

To prepare the child for writing.

#### CONTROL OF ERROR:

The control of error is tactile.

If the child’s finger moves off the sandpaper the difference in texture will be easily noticed.

#### AGE:

3 ½ years approximately.

#### PRESENTATION 1:

- Begin the work cycle.
- Ask the child to sensitise his fingers or to wash his hands in tepid water
- The child sits on your non-dominant side.
- The child carries the numbers to the table. Show him to remove the first three carefully from the box without scraping them.
- Feel the first number with a light, continuous movement with the middle and index fingers of your right hand, holding the board steady with your left hand.
- Proceed with a three period lesson remembering to carefully isolate the numbers in the first and third period.
- Each time a symbol is identified in any stage, it should be felt and then named by the child.

#### PRESENTATION 2:

- Always remember to present one known and two unknown number symbols at a time.
- Always revise the previous numbers and then introduce the new numbers.

#### NOTE:

In tracing the sandpaper numbers, three of the senses are involved:

Tactile – feeling the number

Visual – seeing the number

Auditory – hearing the number

The child only starts to write the number when he has had a lot of practise with the tracing.

#### EXTENSION 1:

- Let the child trace the numbers in a container with flour or fine sand in it. (A high lipped baking tray works well)
- The child traces the sandpaper number and then traces the number into the mealie meal or sand, or into the air or even on the surface of the table.
- Show the child how to shake the container to smooth out the sand.
- Remember; do not correct the child.

#### EXTENSION 2:

- Allow the child to make a RAINBOW number by tracing around a single number a few times using different coloured crayons.
- The child must trace the number in the correct direction, preferably not lifting his pencil unless the number calls for that.

#### EXTENSION 3:

- The child can write in the booklet that the Montessori Directress has made for the child.
- The can be a cover saying, “My 5 book By…”
- Or “My 10 book By …”

#### EXTENSION 4:

- Blindfold the child or place the numbers under a cloth and allow the child to feel the numbers and to try to guess which number it is that they can feel.
- Alternatively, the Montessori Directress can ask the child to feel for a specific number.
