Addition Tables
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
The equations for the Addition Strip Board, printed as tables: nine sheets to a set and five complete sets in the box. Five sets is what lets a group work at once, and the sheets are the part that makes the board a daily material rather than a demonstration, because they supply the problems the adult would otherwise have to invent one at a time. The strip board itself is a separate item. Paper and cardstock.
“The child is both a hope and a promise for mankind.”
The Addition Tables emerge precisely when children demonstrate readiness to record their mathematical discoveries on paper.
- Master addition facts with 1 as the addend through systematic practice
- Develop ability to record mathematical equations in standard notation
- Strengthen number recognition and formation through repeated writing
- Build mental calculation skills by transitioning from manipulatives to paper

These red-printed worksheets mirror the color coding of the Addition Strip Board, creating a visual bridge between manipulative work and written equations. The cardstock sheets present addition facts with 1 as the constant addend, isolating this fundamental concept for focused practice. Dr. Montessori observed that children who have worked extensively with concrete materials naturally seek ways to document their understanding - these Addition Tables fulfill that developmental need. The systematic presentation of equations on each worksheet allows children to perceive patterns in addition, moving from counting individual beads to recognizing number relationships instantly. This transition from concrete to abstract represents a critical moment in mathematical development, when the child's mind begins to operate with numbers as mental concepts rather than physical quantities.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place Addition Tables on a tray with a red pencil. Ensure child has completed extensive work with Addition Strip Board and understands the concept of addition through concrete materials.
