I've designed this Lesson to allow students to explore adding and subtracting negative numbers building up from the basic pictorial through the use of counters and coming to identifying quicker methods/ rules.
It begins with a look a counters and there meaning and different ways of representing numbers and a mini whiteboard activity.

This then leads to 4 basic examples of questions such as -2 + 3, followed by four questions for students to try. Answers are given with full pictorial and written solutions here.

This then leads to 4 examples of questions such as -2 - -3, again followed by four questions for the students to try. Answers are given with full pictorial and written solutions here.

This leads to a class discussion on quicker methods now that they why is understood. Student have the pictorial to fall back on if they get stuck.

There is a pointless quiz activity with two rounds which can be used to help stop misconceptions before the main differentiated activity. (Teacher Guidance notes are within the slides for this activity, however it's pretty straight forward if you have seen the TV show.)

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 5 separate sections a skill 1, 2 & 3 and a stretch 1 & 2. These are all displayed on the same slide for ease of use.

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.

Bonus Materials
There is an extra challenge slide of an additions grid of negative numbers.
There is also a mixed challenge activity to be used with students once they have learnt how to multiply and divide negative numbers also.
I have attached printable versions of the grid I use throughout the slides. I often laminate them for the students to do the examples with me in lessons)
