Add Fractions with the Same Denominator Using Bar Models: Example Question
31 October 2026
Adding fractions with the same denominator can feel much easier when you use bar models. These models help children see exactly how many parts are being added together, making the process clear and visual.
Example question
What is 1/4 + 2/4?
Step 1
Draw a bar. Divide it into 4 equal parts. Shade 1 part to show 1/4.
Step 2
Draw another bar the same size. Divide it into 4 equal parts. Shade 2 parts to show 2/4.
Step 3
Count how many parts are shaded in total. 1 part from the first bar and 2 parts from the second bar. 1 + 2 = 3 parts shaded.
Step 4
The bars are both divided into 4 parts, so the denominator stays 4. The answer is 3/4.
Key insight: When adding fractions with the same denominator, add the top numbers (numerators) and keep the bottom number (denominator) the same.
Answer
1/4 + 2/4 = 3/4.
After working through this example, your child will spot that when the bottom numbers match, they just add the top numbers and keep the denominator the same. They're now ready to practise more questions just like this, using bar models for support.
