The Decimal Fraction Exercise Activity Set: 2 is a Mathematics Montessori material designed for children aged 3-6, crafted by Nienhuis Montessori to AMI standards.
This Decimal Fraction Exercise Activity Set provides systematic practice with decimal concepts through organized card work. The wooden storage box with numbered dividers (1, 2, 3) contains multiple sets of printed exercise cards, allowing children to explore decimal relationships and equivalencies through hands-on manipulation and visual comparison.
“Children display a universal love of mathematics, which is par excellence the science of precision, order, and intelligence.”— Maria MontessoriThe Discovery of the Child
“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.'”
— Maria Montessori, The Absorbent Mind
The Decimal Fraction Exercise Activity Set introduces decimal concepts through organized card work that builds upon the child's existing understanding of whole numbers. Each numbered divider in the wooden storage box represents a specific category of decimal work, allowing children to progress systematically from simple tenths to more complex decimal relationships. The printed exercise cards provide visual representations that connect abstract decimal notation to concrete quantities, essential for ages 3-6 when children transition from purely sensorial mathematics to symbolic representation. By manipulating these exercise cards and comparing decimal equivalencies side by side, children discover that 0.5 equals 5/10 through their own exploration rather than memorization. The wooden storage box with its numbered compartments reflects the Montessori principle of ordered presentation, where each set of cards builds upon previous understanding in a carefully sequenced progression.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Begin with cards from compartment 1, laying them horizontally to show decimal progression from 0.1 to 0.9
Introduce matching work by pairing decimal cards with their fraction equivalents
Progress to compartment 2 cards, exploring hundredths and their relationships to tenths
Create ordering exercises using mixed decimal values from different compartments
Every material is carefully selected for durability, safety, and authentic Montessori experience.
The smooth wooden storage box provides durability while teaching children to care for mathematical materials with respect and organization.
Each material supports multiple areas of child development simultaneously.
Builds concrete understanding of decimal place value and relationships through systematic card exercises.
Numbered dividers teach sequential thinking and help children organize their mathematical work progressively.
Bridges the gap between concrete fraction materials and abstract decimal notation through visual representation.
Self-contained system allows children to select appropriate challenge levels and work at their own pace.
Designed for child-sized hands
Professional tips from AMI-trained guides to maximize the educational value of this material.
“Present compartment 1 cards only until child demonstrates mastery of tenths”
Use precise mathematical language when discussing card relationships
Allow children to create their own card arrangements before suggesting patterns
Store completed work in sequence within compartments for easy progress tracking
Everything you need to know about this material.
This set is designed for children ages 3-6 who have been introduced to basic decimal concepts. However, in Montessori education, readiness is based on individual development rather than strict age ranges. Children should have experience with golden bead material and basic place value before beginning decimal fraction work.
The set includes multiple printed exercise cards organized in three numbered dividers (1, 2, 3). The cards present decimal fraction exercises in a sequential progression, allowing children to practice decimal relationships, equivalencies, and conversions through visual and manipulative activities.
Children work through systematically organized exercises that build understanding of decimal fractions step by step. The cards provide visual representations and activities that help children discover relationships between whole numbers and decimal fractions, supporting concrete understanding before moving to abstract concepts.
While the exercise cards can be used independently, they work best in conjunction with Montessori decimal fraction materials such as decimal fraction boards, cubes, and squares. These concrete materials help children physically manipulate quantities before working with the more abstract card exercises.
Children begin with cards in section 1, which introduce basic decimal fraction concepts. Section 2 presents more complex relationships and equivalencies. Section 3 offers advanced exercises combining multiple decimal concepts. Children should master each section before progressing to ensure solid understanding.
