A hundred green arithmetic books in the large format. A second colour is not decoration in a classroom of thirty: it lets a teacher keep two kinds of work physically apart on a shelf, or give a group their own colour, so nobody has to open a book to find out whose it is or what is in it. Same size and same paper as the blue, and the two are usually bought together for that reason. Paper and cardstock, for ages 3 to 12.
“Education is a natural process spontaneously carried out by the human individual, and is acquired not by listening to words but by experiences upon the environment.”
The Large Green Arithmetic Books serve as the bridge between concrete mathematical manipulation and abstract written computation in Montessori mathematics. These gridded books address the child's need for order and precision when recording mathematical discoveries made with concrete materials. The green color specifically designates these books for arithmetic work, creating visual organization within the mathematics area.
Each precisely gridded page provides structure that allows children to maintain proper digit alignment, essential for understanding place value and accurate calculation. The large format accommodates the child's developing pencil control and need for spacious work areas. These books transform the abstract process of recording mathematics into a concrete, manageable task. The grid system within each book creates boundaries that help children organize their mathematical thinking spatially. Having 100 books ensures every child can document their mathematical journey without waiting, honoring the principle of uninterrupted concentration. The arithmetic books make visible the child's mathematical reasoning process, creating a permanent record of their computational discoveries.


Follow the Montessori method of presentation for optimal child development.
Place arithmetic books in the mathematics area near concrete materials. Ensure sharp pencils are available. Demonstrate proper grid usage with one square per digit.
Show how to write one digit per square, starting from the right for units
Demonstrate recording a simple addition problem worked with golden beads
Guide the child to record their own equation after material work
Show how to draw the operation symbol and equals line using the grid

Grid lines guide proper digit alignment for place value understanding and accurate computation.
Writing numbers within grid squares refines pencil control and develops precise hand movements.
Present the books only after substantial concrete material work, rushing to abstraction hinders understanding

Contact Our ExpertsThese books feature precisely gridded pages that help children maintain proper alignment when writing numbers and equations. The grid system supports the concrete-to-abstract progression in Montessori mathematics, allowing children to organize their work systematically while developing number sense and operational understanding.
Each large arithmetic book contains approximately 32-48 pages of quality gridded paper. The 'large' designation refers to both the book size (typically A4 or similar) and the grid spacing, which accommodates young children's developing fine motor skills and larger handwriting.
In Montessori education, green is traditionally associated with mathematics materials. This color coding helps children identify mathematical work and creates visual consistency across the mathematics curriculum. The green cover serves as a visual cue that reinforces the purpose of these books.
Children can record all four operations (addition, subtraction, multiplication, division), practice number writing, document work with golden beads and stamp game, record skip counting patterns, and solve word problems. The grid format supports everything from simple equations to multi-digit operations with regrouping.
A set of 100 books typically lasts one academic year for a classroom of 20-25 children working regularly with mathematics materials. Each child may use 3-5 books throughout the year, depending on their mathematical progression and the frequency of recorded work versus hands-on material manipulation.
