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.
Fractions are a sum of unit fractions (5/4 = 5 x ¼ = 1 ¼ or 5/4 = ¼ + ¼ + ¼ + ¼ + ¼ )
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).
Discussion Questions
Before the Game
What is an improper fraction? When adding or subtracting fractions with like denominators, does the denominator remain the same in the final answer? How do you turn an improper fraction into a mixed number?
After the Game
If the numerator and the denominator are equal in a fraction, what is the fraction equal to? What strategies did you have to use to subtract mixed numbers? How do we add/subtract fractions with unlike denominators?
