UKS2 (Year 5 and 6) multiplying quantities by fractions, finding quantities given fraction quantity
Learning Objectives
Starter:
To compare improper fractions and mixed numbers
Main Lesson:
To multiply proper fractions and mixed numbers by whole numbers, supported by materials and diagrams (Year 5)
To associate a fraction with division (Year 6)
To find a whole quantity given the quantity represented by a unit fraction (Y6)
To recognise and use relationships between operations including inverse operations (KS3
This lesson consists of:
A Starter consisting of a series of progressively harder problems where the children have to compare mixed numbers with improper fractions and use <> sign to show which are larger. A connect activity challenging children to consider whether the product of two numbers always produces a larger numbers as a way to start considering the effect of multiplying by fractions.
An Interactive Whiteboard teaching introduction for both Notebook and ActivInspire flipchart, to teach children to understanding how to multiply whole numbers by fractions (by dividing by denominator and multiplying by numerator (starting with diagrams) and how to find the whole quantity of a number, when they are given what a fraction of that number represents.
A 4-way differentiated series of tasks requiring children to multiply whole numbers by fractions and find whole numbers when they are given what a fraction of that number represents (i.e. ¾ x ? = 24). Answers included to ease marking.
A final AFL / Next Steps task, providing three answers to a SATs question and children are invited to use the methods they have learned to work out which is correct.
