This week we will be revising and learning more about

Doubling and Halving. 


As a warm up on a Monday and Wednesday you will be asked to fill out a Big Maths CLIC or Learn its sheet as it is very important that you keep practicing the skills we have learnt so far this year. If there are any sums you are unsure how to answer, please let us know via Teams  or email and we can give an explanation to you.


Day Activity Links

As a warm up we would like you to complete the following Learn its sheet. Try and answer as many questions as you can in the time limit!


Doubling means to make a number twice as big. Whenever we double a number the answer is always a lager number. In the past we have used diamond doubling to double numbers. Watch the video as a reminder how to diamond double and then complete the sums using the same method. You must show your working out at each stage of the diamond.

Remember you have 1 minute and 30 seconds to complete the Learn its sheet. Any you do not complete can be completed after the timer but will not go towards the score - please be honest! Only then will you see real improvement 


How to Diamond Double


Diamond Doubling Questions




Tuesday Yesterday you had a go at mainly doubling 2 digit numbers where no digits were larger than 10 when doubled. Today we would like you to complete these two digit number doubles where the ones number is larger than 5. You had a go at this on the last 4 questions of yesterday's work. Watch this video for help first:

Doubling Questions


Begin by completing the CLIC sheet. Try your best to answer all of the questions and if you are stuck on how to answer any let us know.


Today we are going to look at the opposite of doubling - halving. Whenever you halve a number you are making it smaller. Half the size that it was.  Use the diamond method to halve these numbers. Remember, where you would usually double, you will need to halve this time. Watch the video for a quick demonstration.

Halving Questions


You may have noticed that the numbers you were asked to halve yesterday were all made up of even digits. That is because even numbers are much easier to halve. Today you are going to be halving numbers with odd tens digits. 

You will need to watch the video tutorials that show you how to do this. Then have a go at answering the questions.

Halving odd tens 


Today you are going to use everything you have learned this week to answer some word problems involving doubling and halving. Read the questions very carefully and look for the key words that will help you decide if you need to double or halve and which numbers to use.
