Here we will cover all elements of our fraction work. We will look at addition and subtraction, multiplying fractions, dividing fractions and finding fractions of amounts.

BIDMAS is an acronym that tells us the order in which we do our operations. It stands for Brackets - Indices - Division - Multiplication - Addition - Subtraction.

An error interval is used to determine the maximum or minimum possible value when a number has been rounded. We will use inequalities to show that the real value can be anywhere in between the maximum and the minimum.

This module is used to find upper and lower bounds from calculations. We will be using our error interval work from the last module and applying this to work with more than one variable.

When we see the word estimate we round every number to an easier, more manageable number. This makes our calculations easier and saves us time.

Converting compound units is not always what we expect. In this video we will show you how to perform repeated small jumps and how to work from a conversion of a singular unit in order to help answer your specific questions.

Standard Form is used to write particularly large or small numbers in a more concise way. It will always be a number between 1 and 10, multiplied by 10 with a power. We will show you how to convert from numbers in to standard form, and how to go from standard form back in to normal numbers.

Now that we can convert between ordinary numbers and standard form, we need to be able to use it. This module is on how to add, subtract, multiply and divide using standard form.

IThis video will explain how we split a number up in to a product of it's prime factors. This basically means all of the different prime numbers that go in to a number. This topic is really important for our next worksheet so make sure you are confident with this before moving on!

Using our product of prime factor work from the last module we can find the highest common factor (HCF) and the lowest common multiple (LCM). The HCF is the biggest number that can go in to both numbers and the LCM is the smallest number that they can both go in to.

The following worksheet will revisit all of the skills you have practiced throughout this block. This is a good chance to see where your number work is at and to get feedback on what may be worth recapping! Try and answer each question to the best of your ability, and if you need reminding you can watch the videos above. Good luck!
