Equivalent Fraction Circles

Help students build a deep visual understanding of fractions with this interactive fraction circle tool. Learners adjust the numerator and denominator using simple vertical sliders on each side of the circle. As they move the sliders, the circle updates instantly—showing exactly how much of the whole is shaded.

Two circles appear on the screen, allowing students to compare fractions side-by-side. When the two fractions represent the same value, both circles automatically turn green, giving immediate visual feedback. Students can also tap the numerator or denominator to enter values directly.

The Random button generates new fraction pairs for quick practice or warm-ups, and the layout is optimized for tablets, Chromebooks, and interactive whiteboards.

Why It Works

• Shows fractions as parts of a whole using clean, child-friendly visuals
• Instant updates make numerator/denominator relationships intuitive
• Vertical sliders encourage fine motor control and conceptual reasoning
• Auto-green highlight reinforces equivalence without distracting animation
• Two side-by-side circles are perfect for comparing fractions or creating challenges

Great For

• Introducing fractions
