Decimal Fraction Exercise Activity Set: 1
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
Exercise cards with divider tabs in a wooden box, extending the decimal fraction exercise. Decimal fractions are where the two halves of a child's arithmetic finally meet: the place value work says every column is ten times its neighbour, and the fraction work says a whole can be cut up, and a decimal is both statements at once, running to the right of the point instead of the left. That is worth many days of work, and these cards are the days. Decimal fraction exercise sold separately. Wood, cardstock and laminate, for ages 3 to 12.
“The hands are the instruments of man's intelligence.”
The Decimal Fraction Exercise Activity Set bridges concrete mathematical experiences with abstract decimal concepts through its laminated task cards and visual representations. Each numbered divider in the wooden storage box creates a physical sequence that mirrors the child's cognitive journey from whole numbers to fractional parts. The visual representations on each card allow children to see decimal relationships before manipulating symbols, addressing the developmental need for concrete imagery before abstraction.
- Recognition of decimal notation and its relationship to fractions
- Understanding place value beyond whole numbers
- Conversion between decimal and fraction forms
- Comparison and ordering of decimal numbers

The wooden box with its systematic organization reflects the mathematical order inherent in the decimal system itself. The laminated exercise cards progress from simple tenth representations to complex decimal problems, respecting the child's need for incremental challenge. This set exists because children require repeated, varied practice with decimal concepts to internalize the base-ten system's extension beyond whole numbers. The numbered dividers create a self-checking system where children can verify their readiness for each level of decimal work.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the wooden storage box on a mat. Remove cards from the first numbered section. Lay out any concrete decimal materials (golden beads, fraction insets) that correspond to the exercise level.
