Today's Lesson
Introduction
Recap and discuss what we have learnt so far about arrays, emphasising that they show that multiplication can be done in any order.
Ask your student to draw an array with 30 or fewer dots.
For example, this could be 4 x 3, 2 x 10 or 6 x 4, but challenge your student to work this out for themselves.
Working with your student as a pair, take turns to say something about what the array shows.
For example, if they chose 5 x 6, you could say, ‘This array shows 5 x 6 = 30 and if I turn it around it shows 6 x 5 =30.’
Then, suggest a ‘real life’ situation for the array.
For example, ‘There would be 30 buns if we had 5 packets of 6 buns.’
Then suggest how we could turn this into a word problem.
For example, ‘Lauren buys 5 packets of buns, each containing 6 buns. How many does she have altogether?
Have the array ready to refer to later in the lesson.
Ask your student to talk with you to make up a word problem about 12 eggs. Can they visualise how they might be grouped?
Emphasise the language: ‘lots of’, ‘groups of’, ‘multiplied by’, ‘divided into groups of’, and so on.
This video will help with seeing how to use arrays to understand multiplication facts.
Main Activity
Use 📄 Multiplication word problems to apply the skill of writing number sentences for arrays and writing word problems for given arrays.
Each of the three sheets gets more challenging. Decide which of the sheets to start on, depending on how well you feel your student has made progress so far.
