Year 5 Maths: Adding Fractions

Hello Year 5! Today, we’re going to learn about adding fractions. This is an important skill in maths, and I’m here to help you understand it step-by-step.

What Are Fractions?

A fraction shows a part of a whole. For example, if you have a pizza cut into 4 slices and you eat 1 slice, you have eaten $$\frac{1}{4}$$ of the pizza.

Adding Fractions

When adding fractions, we need to pay attention to the denominators (the bottom number of the fraction). Here’s how we can add fractions together!

Step 1: Same Denominator

If the fractions have the same denominator, just add the numerators (the top number of the fraction) and keep the denominator the same.

Example:

$$\frac{2}{5} + \frac{1}{5} = \frac{2+1}{5} = \frac{3}{5}$$

Step 2: Different Denominator

If the fractions have different denominators, you need to find a common denominator. This is a number that both denominators can divide into.

Example:

$$\frac{1}{3} + \frac{1}{6}$$

1. The denominators are 3 and 6. The common denominator is 6.
2. Convert $$\frac{1}{3}$$ to have 6 as the denominator:$$\frac{1 \times 2}{3 \times 2} = \frac{2}{6}$$
3. Now add:$$\frac{2}{6} + \frac{1}{6} = \frac{2+1}{6} = \frac{3}{6}$$
4. You can simplify $$\frac{3}{6}$$ to $$\frac{1}{2}$$.

Key Rules

1. Same Denominator: Add the numerators, keep the denominator.
2. Different Denominators: Find a common denominator, convert fractions, then add.
3. Simplifying Fractions: Always try to simplify your answer.

Tips and Tricks

• When you find a common denominator, you can usually use the biggest denominator as a starting point.
• Remember to check if your final answer can be simplified.
• Practice makes perfect! The more you try, the easier it will get.
