Fractions - Mixed numbers to improper (bar model) - Worksheet

The provided worksheet is aimed at teaching Year 5 students the concept of converting mixed numbers to improper fractions using bar models. This lesson aligns with the National Curriculum objective of recognising and converting between mixed numbers and improper fractions. To facilitate learning, differentiated sheets and teaching slides are available as resources. The vocabulary for this lesson includes terms such as improper fractions, mixed numbers, convert, represent, quarter, halves, eighths, fifths, whole, numerator, denominator, multiply, and add. Students are encouraged to use concrete and pictorial methods alongside their working to grasp the abstract mathematical concepts.

Key questions posed during the lesson include inquiries about the number of specific fractions in a whole and how multiplication aids in the conversion from mixed numbers to improper fractions. Students are also asked to explain the conversion steps using the relevant vocabulary. The activities require children to draw bar models in their maths books, showing the mixed number alongside the improper fraction, and to use reasoning skills to find missing parts of the bar models. The worksheet progresses from fluency and precision exercises to reasoning and problem-solving tasks, challenging students to identify and explain errors made in conversions by hypothetical students, thus deepening their understanding of the topic.
