Problem Slips: Addition Working Charts
Rooted in Montessori pedagogy, this addition problem slip set aids the child's work with the Addition Working Charts, providing systematic practice cards organized in clear acrylic containers. Each compartment holds equation cards featuring single and double-digit addition problems with tactile braille elements, and children learn to progress from concrete manipulation to abstract mathematical thinking while developing computational fluency.
“The greatest sign of success for a teacher is to be able to say, 'The children are now working as if I did not exist.'”
The Problem Slips for Addition Working Charts address the child's need for repeated, varied practice with addition equations during the critical period for mathematical abstraction.
- Masters addition facts through systematic practice with equation cards
- Develops computational fluency by working through organized problem sequences
- Builds abstract thinking skills by transitioning from concrete materials to written equations
- Strengthens memory of number combinations through repetitive practice

Each equation card in the acrylic containers presents a specific addition problem, allowing children to work systematically through increasingly complex calculations. The tactile braille elements on each problem slip provide multi-sensory engagement, reinforcing number concepts through touch while the child solves equations. The clear compartment organization reflects Maria Montessori's principle of prepared environment, where materials are arranged to promote independent selection and sequential work. These problem slips bridge the gap between manipulating concrete materials like golden beads and working with abstract numbers, as children can still reference physical quantities while practicing computational skills. The systematic progression from single to double-digit problems respects the child's natural mathematical development, allowing mastery at each level before advancing.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the acrylic container on a mat with the Addition Working Chart. Ensure equation cards are organized by difficulty level in their compartments. Have a pencil and answer sheet ready.
