Lesson 2: Division using a number line


So to begin with, we would like you to mark the questions from yesterday's activity using the answers below. Go through any you didn't understand with someone at home wait until your teacher calls you to discuss it.




Yesterday, we looked at two different strategies to solve division questions: Arrays method and Repeated subtraction on a number line.

Talk to your grown up about how you found them. Which strategy did you manage to understand? Was there anything you found challenging?


Today we will be focussing on repeated subtraction on a number line and trying to get more confident in using this method.

Below is the YouTube clip from yesterday, watch this to remind yourself again on how we use repeated subtraction or watch Mrs Karia's video from yesterday!

Division - Repeated Subtraction on a Numberline

Now there is nothing wrong with using repeated subtraction on a number line for division, however, when the numbers in your question get larger is does pose a little bit of a problem!


1. It takes a really long time!

2. You are more likely to make a mistake!


So to help us solve division questions with larger numbers, we can continue to use repeated subtraction on a number line but we can make our jumps more efficient. This is known as CHUNKING! This method helps you to speed up your jumps on a number line using known facts and therefore get to the answer quicker.


Below is a video to show you how to perform efficient jumps on a number line for division.


Please note: If you prefer to use repeated subtraction on a number line -  please use what you are comfortable and confident with.

Efficient jumps on a number line for Division (Chunking)

So we would like you to practise either repeated subtraction on a number line OR efficient jumps on a number line to solve the following questions below. The main thing to remember is, do the method you feel confident with!

If you get stuck, ask your grown up at home to help you, or contact your teacher by email or await your weekly phone call.


Below is an additional PowerPoint to help you along with the questions we'd like you to complete. We would like you to do at least 8 questions, but again, the more practise you get the better you will be at this! Good luck smiley



If you feel you need a challenge, try these questions below:


  1. 75 ÷ 5 =
  2. 96 ÷ 3 =
  3. 124 ÷ 4 =
  4. 132 ÷ 6 =
  5. 144 ÷ 9 =
