Maths 27.1.22
Here is your starter that you would normally have on the board. This starter is to help keep ticking over things we have already learnt in class.
- 1) 30% of 40
- 2) 55% of 120
- 3) 2% of 140
- 4) 99% of 630
- 5) 25% of 232
Remember to find 10% means to divide the quantity by 10.
5% means to half 10%
1% means to divide the quantity by 100.
25% is the same as ¼ and 50% is the same as ½
Main lesson LO: To use BODMAS
We have started to look at following a certain mathematical order when we are faced with calculations where there is more then one operation to do.
E.g. 2 + 3 x 4 =
Now, if I were to ask you to solve this, you might end up with two answers. E.g. 2 + 3 = 5 x 4 = 20 or 3 x 4 = 12 + 2 = 14. It’s impossible to end up with two different answers therefore, we must follow an order.
We call this BODMAS or BIDMAS (means the same thing!) It is effectively a checklist/an ordering in which we must follow in order to answer the question correctly. Please see the poster below to help you remember the order. So if I have followed the order right I should have done the 3 x 4 = 12 first, then + 2 = 14.

I have done a small PP to help you introduce the topic and have gone through a couple of examples. BODMAS PP
You have 3 options for your work.
Option 1 – This is the support sheet for this lesson. It’s fairly simple but it might give you the confidence as you start off on this lesson. Lesson 3 Support BODMAS
Option 2 – To use the Busy Ants book we use at school and focus on Challenge 1 and Challenge 2. BODMAS maths lesson BA
Option 3 – If you fancy a challenge. These are trickier but you need to follow the BODMAS order in order for you to crack the code. BIDMAS Crack the Code Worksheet

Maths 28.1.22
Starter- Here is today’s starter, please complete. Friday’s starter
Main lesson
Today’s lesson is a revision lesson in all thing’s calculation. We want to see that you have the strategies perfected for all four operations. The questions are a mixture of worded and normal. Make sure you put one digit in each box and give the decimal a box all to itself if you need to.
You know how the books work.
Challenge 1 – Easiest- Make sure you read whether the questions are addition or subtraction.
Challenge 2 – Medium but you will need to read the worded problems carefully in case there are multiple steps.
Challenge 3 – Slightly more challenging. If you complete this challenge this will also help you revise percentages (%) too!
You do not need to answer all of the questions, but we would like you to complete an entire challenge please.
