Elementary school children practice the values ​​of numbers up to 100 with the board of hundreds. The relationships between horizontal and vertical structures can be clearly seen from the arrangement of the numbers in the grid. The child recognizes neighboring numbers, even / odd numbers and full tens when laying out the matching number tiles.

Application, advantages, areas of application for this Montessori material:

• • Lay out all the numbers in the correct order

• • Interpret only even numbers

• • Interpret only odd numbers

• • Lay out all the numbers that start with a 5

• • Interpretation of all tens

• • Interpretation of all multiples of a number

• • Montessori material for children from 5 years

Scope of the Montessori material:
1 board of hundreds with grid lines, wood, approx. 29 x 29 x 1.5 cm
100 number plates 1 to 100, wood. approx. 2.5 x 2.5 cm
1 wooden box for storing the number plates, approx. 24 x 8.5 x 3 cm
1 separate control board, wood, approx. 29 x 29 x 1 cm

Instructions for the Hundred Board

It is very helpful if the number plates are sorted into groups of ten first.
This first assignment of the tiles to groups (this tile belongs to the 20s, this to the 50s, etc.) structures the mess of tiles and provides first insights into the structure of the number range up to 100.
The number tiles are arranged in stacks or piles ( ie one after the other, 0-9, 10s, 20s, 30s etc.), the hundreds board is next to it.
The adult places the numbers 1 to 100 one after the other on the board of hundreds, with 10 tiles lying next to each other in a row. The number is clearly spoken for each tile.
If all the tiles are on display, they can be compared with the control card.
Then the tokens are collected again and it is the child's turn.

Variations: At
first, the child only works with the control card and the tiles. The appropriate tile is placed on each number.
Only then is the hundred board added. Now the digits are placed in the correct order on the hundred board. The control card is used to support this.

The adult puts in some numbers and the child moves on.

On the fully laid out board of hundreds, any tiles are removed, placed in a bowl or simply put to one side, and then reinserted in the right place. This assumes a good orientation in the hundreds field.

Any number tiles are laid out, the child lays out the corresponding neighboring numbers (e.g. 53 is laid out, the child adds 52 and 54). This predecessor-successor game can also be played in the tens range. The number 48 is interpreted, for example. The child places 38 (the predecessor of tens) and 58 (the successor to tens).
