Mathematics

The exercises of Practical Life and Sensorial provide the foundation for mathematics.  The work that the child has been doing everyday with sorting, comparing sizes and shapes, patterning, classifying and putting things in order have already helped form the young child’s mind for a life- long love of mathematics.
The Montessori Math materials allow the child to physically manipulate materials in order to form a concrete understanding of math that will make it easier to understand the abstract concepts to come.

The Sandpaper Numerals are presented a few at a time having the child
trace to learn the correct formation and name of each numeral.

 

The red and blue number rods introduce numerical order and quantity of 1 – 10 . The children are familiar with the number rods,
they are the same dimensions used earlier in the sensorial area of the classroom presenting length – short to long.

 

The Spindle Box introduces the numeral zero. The Spindle Box provides practice placing
the correct amount of spindles next to the correct numeral in numerical order.

 

The math area can offer seasonal interest. The apple trees still help the child be independent of the teacher with the control of error.

 

There are many Montessori materials that help the child with simple adding and subtracting. The Addition Board
offers the child easy visual clues. The older child takes great pride in writing his answers.

 

After having an introduction to the decimal system, the child is able to lay out numerals and quantity for units, tens, hundreds and thousands.

 

The Small Bead Frame helps the child transition from a semi-abstract to a more abstract
understanding of the exercises of addition and subtraction into the thousands.

 

The Division Board helps the child practice using dividends and divisors. This is always a loved exercise.

 

This excercise replaces the larger decimal bead material and replaces each place value with a colored square.
With this work you can do addition, subtraction, division, multiplication, and exchanging place values.

 

Linear and skip counting is done with long chains presenting an amazing impression. The ten chain is almost as long as the classroom.
