Instructions

Play through this interactive game to learn about Unit Fraction Multiples Multiplying Whole Numbers. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Apply previous understanding of multiplication that 3 x 7 can be represented as the number of objects in 3 groups of 7 objects, and write this as 7 + 7 + 7 to multiplication of fraction by a whole number.

See a fraction as numerator as a whole number multiplied by the unit fraction with the same denominator ( 9/5 = 9 x 1/5).

All fractions are a composition of their unit fraction.

Unit fractions or fractions with a numerator of 1, which are formed by partitioning a whole into equal parts and taking one part. e.g. If a whole is partitioned into 3 equal parts then each part is 1/3.

Unit fractions are to be understood to be the basic building block of all fractions.

Multiply a whole number and a fraction by using the reasoning of the whole number multiplier as groups of the fraction to be added together (3 x 2/5 as 2/5 + 2/5 + 2/5 = (3 x 2)/5 = 6/5).

Discussion Questions

Before the Game

How do you know if two fractions are equivalent? If the number on top of a fraction is larger than the bottom number, what does that mean? What is the unit fraction for 3/4? How do you add a whole and a fraction?

After the Game

How do you add fractions with the same denominators? Do you need to change fractions in order to add them? Do you need to change any part of a fraction in order to multiply them? Can you explain how you compared the fractions shown in pictures with the number fractions?
