Adding Fractions with Like Denominators

Adding Fractions with Same Denominator

Adding fractions is an important skill and grade 3 is a fantastic time to start introducing it! The ability to add fractions with the same denominator is not tricky, it just takes practice. Students are often quick to forget simple concepts in Mathematics, which is why it is so important to introduce adding fractions to students in grade 3. It gives them time to understand and develop their knowledge, not just in the math involved, but the actual concept of a fraction and adding them together. As students move into grade 4, they’ll have a solid foundation and begin to add fractions with unlike denominators, which can be a bit tricky and requires further repetition!
