Instructions

Play through this interactive game to learn about Mixed Numbers with Like Denominators. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Use visual models to show that unit fractions compose fractions.

Adding and subtracting fractions is similar to whole number computation in that it is adding or subtracting two number line quantities.

A mixed number is a whole number plus a fraction smaller than 1, written without the sign, e.g. 5 3/4 means 5 + 3/4 and 7 1/5 means 7 + 1/5.

Use equivalent fraction for mixed number by converting whole into a composition of unit fractions. 1 ¼ = 4/4 + ¼ = 5/4.

Add mixed numbers by using equivalent fractions with the same denominator (1 ¼ + 2/4 = 5/4 + 2/4 = (5 + 2)/4 = 7/4).
