Lowest Common Denominators
In this worksheet, students learn to find the lowest common denominator between two related denominators. It is a part of a larger unit designed to help students learning consolidate equivalent fractions skills for Year 4.
Learning goals
- We are learning to investigate equivalent fractions, e.g. halves, quarters and eighths or thirds and sixths.
- We are learning to find equivalent representations of fractions and make connections between fractions and decimals, e.g. ¼ of 1 metre = .25m or 25cm.

Extensions
There is a further level of lowest common denominator that can be found in the sequel to this worksheet. It is at a level that is most likely above year 4, but could be used to extend students.
