In this unit we shall look at the basic concept of fractions — what they are, what they look like, why we have them and how we use them. We shall also look at different ways of writing down the same fraction.
Compare unit fractions with different denominators (e.g. 1/3, 1/4, 1/5). Compare fractions with the same denominator (e.g. 1/5, 2/5, 3/5). Encourage strategies for deciding whether a fraction (unit or non-unit) is less than half, equal to half or greater than half.
A fraction is in simplest form, or reduced form, when the numerator and the denominator have no common factors other than 1. To write a fraction in its simplest form (lowest terms), divide both the numerator and denominator by the greatest common factor (GCF) that divides evenly into both numbers.
