I've designed this resource to allow students to start to understand substitution from the basics upwards. It begins with a stopwatch starter asking students to simplify basic algebraic expressions.
This leads to a restaurant menu activity and a class discussion about how they intrinsically know how to substitute to find the total cost.
I've found it's important to look at the language of mathematics to help students understanding. I find a perfect activity for this topic is connections, here students have to make links related to substitution and the words on the page, I've provided an example and then some possible answers for this. This means moving forward I can use mathematical language, such as variable, and be sure the students understand it's meaning.
Afterwards there is a quick true or false activity with the answers, you could do this as a mini whiteboard activity, class discussion, group task or silent focus. I personally use this with whiteboards and hammer out the misconceptions. It is a good tool in getting the students to practise providing explanations and reasons verbally for their answers.
I've then modelled 4 different examples of varying ability and these appear step by step and include examples with negative numbers.
There is then a catchphrase quiz activity which I find useful to hammer out any misconceptions the students may have. (The answers or on the next slide for this, some teachers may find it useful to jot these down or print that slide before completing the interactive activity). The catchphrase is bad hair day.
The resource then in includes a differentiated focused activity which progressively gets harder. This gives students a chance to master and enhance their skills. It includes 4 separate sections a skill 1 & 2 and a stretch 1 & 2. These are all displayed on the same slide for ease of use. (Answers are provided)
Then to finish there is an application on how this could be seen in an exam situation including answers.
I hope you find this resource as useful as my students have.
