Gizmo of the Week: Modeling Fractions (Area Models)

Visualizing fractions is easy in the Modeling Fractions Gizmo. In this Gizmo, students can change the denominator and the numerator to see the effect each has on the shaded area of an area model. Students can compare fractions with the lowest common denominator and use this visual to understand how the difference between two fractions is determined.

Understanding denominators and operations with fractions can be challenging for many students. Questions like “Why is 3/6 bigger than 3/7?” or “Why does 2/6 + 1/3 not equal 3/9?” are made simple using the area model approach of the Modeling Fractions Gizmo.
