Introduction to Adding Fractions

Hello Year 6! Today, we’re going to learn about adding fractions. Fractions are parts of a whole, and sometimes we need to add them together. Don’t worry; it’s easier than it sounds!

Understanding Fractions

Before we dive into adding fractions, let’s remember what a fraction is. A fraction has two parts:

  • The top number is called the numerator. It tells us how many parts we have.
  • The bottom number is called the denominator. It tells us how many equal parts the whole is divided into.

For example, in the fraction \frac{3}{4}

:

  • The numerator is 3 (we have 3 parts).
  • The denominator is 4 (the whole is divided into 4 equal parts).

Adding Fractions: Key Rules

When adding fractions, there are a few important rules to remember:

  1. Same Denominators: If the fractions you are adding have the same denominator, just add the numerators and keep the denominator the same.
    • Example: \frac{1}{4} + \frac{2}{4} = \frac{1+2}{4} = \frac{3}{4}
  2. Different Denominators: If the fractions have different denominators, you need to find a common denominator before adding.
    • Example: To add \frac{1}{3}
      and \frac{1}{4}
      :
      • The common denominator of 3 and 4 is 12.
      • Convert the fractions:
        • \frac{1}{3} = \frac{4}{12}
          (because 1 \times 4 = 4
          and 3 \times 4 = 12
          )
        • \frac{1}{4} = \frac{3}{12}
          (because 1 \times 3 = 3
          and 4 \times 3 = 12
          )
      • Now add them:\frac{4}{12} + \frac{3}{12} = \frac{4+3}{12} = \frac{7}{12}
  3. Simplifying: Sometimes after adding, you might need to simplify the fraction (make it smaller).
    • Example: \frac{4}{8}
      can be simplified to \frac{1}{2}
      .

Tips and Tricks

  • Always check if the fractions have the same denominator first.
  • Use a number line to visualize the fractions if you’re feeling stuck.
  • Practice makes perfect! The more you work with fractions, the easier it gets.
