Multiplication and Division Methods - The Complete Series (5 lessons)

They will apply their knowledge and understanding of these methods when solving a range of fun, party-themed problems.

This five-lesson scheme of work comes with a detailed lesson plan, differentiated activity ideas, lesson input slides as well as printable resources.

In this first lesson, children will recap on their knowledge of the grid method for multiplication, and apply it to real-life problems in the context of party planning and using money. Children are also challenged to spot mistakes in given grid methods, and use their understanding to correct them. In their independent activities, children will use this method to work out the costs of different party items, or in the alternative activity, find and correct errors in given calculations.

In this lesson, children will be introduced to the expanded method for multiplication. They will first multiply two-digit numbers by a one-digit number, then move onto multiplying three-digit numbers by a one-digit number, discussing the extra steps that are needed. Children will compare the grid method and the expanded method, discussing the similarities and differences and their own personal preference. In their independent activities, children will apply this method in order to work out the amounts of different ingredients needed for baking cakes.

Children will recap on their knowledge of the repeated subtraction method for division. They will be challenged to explain why a remainder will always be smaller than the divisor. Children will apply this method to their independent activities when calculating how much of each party food different numbers of children can have. Alternatively, they use the Pic ‘n’ Mix cards to work out how many of each type of sweet they can buy with a given amount.

Children’s knowledge and understanding of the chunking method for division is recapped on in this lesson. They will discuss and explain when it is better to use this method instead of repeated subtraction. Children will learn that it doesn’t matter what size chunks they use as long as their calculations are correct! Children will apply this method when playing the Snap Challenges or Remainder Round Up game.

In this final lesson, children will discuss the methods they have used for multiplication and division so far, and explain how to solve different word-based problems using them. Children will then apply all of their knowledge and understanding to solve multiplication and division problems based on different party trips.
