What is the hundred board in Montessori?
The hundred board is a wooden board with a 10×10 grid and 100 numbered tiles that children place in order from 1 to 100. It helps them understand the sequence of numbers and the patterns of the decimal system, such as each row starting with the next ten.
What this means in practice
It is used after children understand quantity with beads and numerals.
