Subtraction Tables Booklet: 2
The subtraction tables from eighteen down to one, this time with the subtrahends shuffled. Subtraction is where random order bites hardest, because a child who has been counting back finds the count is now a different length every line and cannot be set up in advance. Fingers stop being fast enough, which is exactly the pressure that turns counting into knowing. Twenty four booklets. Paper and cardstock, for ages 3 to 12.
“Free the child's potential, and you will transform him into the world.”
The Subtraction Tables Booklet 2 addresses the mathematical mind's need for systematic practice with larger numbers, specifically focusing on subtracting from 11 and 12.
- Memorization of subtraction facts for numbers 11 and 12
- Development of mathematical fluency through systematic practice
- Recognition of number patterns in subtraction sequences
- Building concentration through focused equation work

This booklet provides the abstract work that follows concrete manipulation of golden beads and subtraction strip boards, allowing children to internalize these specific number relationships. The structured pages of the Subtraction Tables Booklet 2 isolate each equation, enabling focused attention on one mathematical fact at a time. By concentrating on just two numbers (11 and 12), the booklet respects the child's capacity for gradual mastery while building toward complete memorization of subtraction facts. The booklet format encourages independent work cycles, as children can complete pages at their own pace and return to challenging equations as needed. This progression from concrete materials to the written equations in the Subtraction Tables Booklet 2 exemplifies how mathematical abstraction develops naturally when properly sequenced.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the booklet on a table mat with a pencil. Ensure the child has previously worked with subtraction strip board and understands the concept of taking away.
