Decimal Fraction Exercise Activity Set: 2
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
The second set of exercise cards with divider tabs in a wooden box for the decimal fraction exercise. The first set gets a child reading and building decimals; the second is where they have to be operated on, and that is where the old habits bite, because lining up a decimal point is not the same rule as lining up the right hand digit. Enough graded problems to work through the confusion is the only thing that fixes it. Decimal fraction exercise sold separately. Wood and cardstock, for ages 3 to 12.
“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 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.
- Understanding decimal place value through visual card comparison
- Recognizing equivalencies between fractions and decimals
- Reading and interpreting decimal notation to tenths and hundredths
- Ordering decimal quantities from smallest to largest

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.

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 divider 1 first. Ensure work space allows for horizontal card arrangement.
- 1
Begin with cards from compartment 1, laying them horizontally to show decimal progression from 0.1 to 0.9
Allow child to discover the pattern before explaining - 2
Introduce matching work by pairing decimal cards with their fraction equivalents
Start with obvious matches like 0.5 and 5/10 - 3
Progress to compartment 2 cards, exploring hundredths and their relationships to tenths
Use language like 'ten hundredths equals one tenth' - 4
Create ordering exercises using mixed decimal values from different compartments
Let child self-check by flipping cards to verify sequence
