Fraction 4A
Overview
In this Phlow, learners are introduced to fractions as “parts of a whole.” Each screen displays a shape divided into equal sections, some shaded and some unshaded. Students identify which fraction of the shape is shaded and match it to the correct numerical form (e.g., ⅓, ¼, ⅔).
The activity develops understanding of three key ideas:
- Equal parts are required for a valid fraction.
- The numerator represents shaded parts.
- The denominator shows total parts making up the whole.
Worked Example
- A circle is divided into 4 equal parts.
- 3 of those parts are shaded.
- Fraction represented: 3/4 (numerator = 3 shaded parts, denominator = 4 total parts).
Sample Questions
- What fraction of this rectangle is shaded?
- How many parts make up the whole shape?
- Which is the numerator in the fraction 2/5?
- Which fraction shows one half shaded?
By completing this Phlow, students gain confidence in interpreting and constructing fractions from visual cues, forming the conceptual foundation for comparing, simplifying, and calculating with fractions later on.

Prerequisite Knowledge Required
- Shape 3B – Understanding equal parts in basic 2D shapes
- Division 3A – Recognising “equal sharing” and partitioning ideas
- Number Line 3C – Interpreting positions between whole numbers
Main Category
Number → Fractions & Proportion
Estimated Completion Time
Approx. 8–12 seconds per question.
30 questions total → Total time: 4–6 minutes.
Cognitive Load / Step Size
Low. Each question isolates one cognitive action — counting shaded parts, counting total parts, or matching notation. Gradual introduction of key vocabulary ensures comprehension before symbolic reasoning begins.
Language & Literacy Demand
Low to moderate. Prompts are short and predictable (“Which fraction is shaded?”). Colour cues and visual supports carry most of the meaning. Key fraction terms are highlighted to support vocabulary acquisition for all learners.
Clarity & Design
- Simple, geometric visuals with high-contrast shading.
- Consistent use of purple for focus terms (numerator, denominator).
- Minimalist layout keeps attention on shape and proportion.
- Handwriting animation reinforces the concept step-by-step.
Curriculum Alignment (ROI Junior Cycle Mathematics)
- Strand: Number
- Strand Unit: Fractions
- Learning Outcomes:
- Understand fractions as equal parts of a whole.
- Identify numerator and denominator in both visual and symbolic forms.
- Represent fractions using shapes, words, and symbols.
- Recognise unit and simple non-unit fractions (½, ⅓, ¾, etc.).
Engagement & Motivation
High. Vibrant visuals and immediate feedback promote active participation. The simple, recognisable context of shaded shapes supports flow and intrinsic motivation.
Error Opportunities & Misconceptions
- Counting shaded parts incorrectly or omitting unshaded parts.
- Believing unequal parts can still represent fractions.
- Reversing numerator and denominator.
- Assuming larger denominators always mean larger fractions.
Transferability / Real-World Anchoring
Moderate to strong. The skill applies directly to everyday sharing, cooking, measurement, and dividing items fairly — turning abstract mathematics into practical reasoning.
Conceptual vs Procedural Balance
Conceptually weighted. Students develop visual intuition about “part–whole” relationships before moving on to procedural manipulation, laying a foundation for equivalence and operations with fractions.
Learning Objectives Addressed
- Recognise fractions as equal parts of a whole.
- Identify numerator and denominator accurately.
- Match visual representations to symbolic forms.
- Develop reasoning about fraction size and equality.
What Your Score Says About You
- Below 20: You may be unsure about numerator and denominator — revisit fraction structure.
- 21–29: You’re developing understanding — practise linking shaded parts to total parts.
- 31–39: You show solid visual and symbolic recognition of fractions.
- 40 / 40: Excellent! You fully understand fractions as equal parts of a whole.
