The Addition & Subtraction Table with strips is a table that resembles the Montessori addition and subtraction table.

The child counts the boxes of the quantities he adds or subtracts, helping them to understand the operations of addition and subtraction from this visual activity. Importantly, the different sizes of the wooden strips provide an understanding of the size, meaning 1 is less than 3 and that it is twice the size of 2.

Includes:

• a strip chart where each box represents a quantity
• 9 red stripes with different sizes
• 9 blue stripes with different sizes
• 19 strips in wood colour (for removal)

This product is a design of Greek Montessori.
