Teaching repeated addition is a way to improve multiplication fluency for students who can’t learn their multiplication facts. Teaching repeated addition will help students to build their understandings about multiplication using what they already know about addition. It is a simple strategy that you can implement into your maths routines, but one that will produce results quickly! take a look at these classroom ideas that you can use today for teaching numeracy
Students who find it difficult to learn how to multiply do so as a result of being taught ‘times tables’ chants before being taught what multiplication is. Think about it this way. When you hear a student proudly sing the ABC song you know that all they can actually do is sing a song. You know that just because they can sing a song it doesn’t mean that they have any understanding about reading, writing, phonics or spelling. So when we see students who know their ‘times tables’ we should not assume that they understand what multiplication is.
Students who struggle with multiplication do not understand that multiplication is the repeated addition of the same number. When they see a multiplication problem e.g. 4 X 2 they will tell you that they need to ‘times it’ but they don’t know what to ‘times it’ really means.
To help fix this teachers need to teach students how to extend what they already know about addition into repeated addition and then link this to the process of multiplication.
Teaching Repeated Addition
Repeated addition is the easiest way to solve multiplication problems but it requires students to be able to interpret a multiplication problem correctly. For example the problem 2 x 4 would be 2 added together 4 times. Take a look at this short video.
To help students make the transition from additive into multiplicative understanding it is important to explicitly teach how the two processes are connected. To solve any type of maths problem we suggest using Dr. Anne Newman’s prompts to facilitate student learning when teaching numeracy
Here is an example of the steps to solve: 4 x 2 = ?
- The first step is to discuss what the problem is asking us to do. Use the prompt:”What is the problem asking you to find out?”
- Next model to the students how to put the problem into their own words.
- Provide explicit instruction on how to replace ‘times’ or ‘multiply’ with the words ‘groups of’ or ‘lots of’ to ensure understanding.
- Demonstrate how to create the repeated addition number sentence to match the multiplication problem.Students will need know:
- Which number they should add over and over
- When to stop adding
- Use materials, drawings and number lines to find the solution
- Finally, test the solution works
Planning Classroom Activities
Improve understanding of the repeated addition strategy by providing opportunities for your students to try out the repeated addition process.
