I’ve designed this Lesson to allow students to explore multiplying and dividing negative numbers building up from the basic pictorial through the use of counters and coming to identifying quicker methods/ rules.
This then leads to 6 basic examples of mutliplication questions such as -2 x 3 and -2 x -3. The examples are broken into to groups of 2 and are each followed by four questions for students to try. Answers are given with full pictorial and written solutions.
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 then a similar structure for division of negative numbers.
A true or false activity to be used as a discussion point over the generalisation of how rules work.
There is a Bingo quiz activity which can be used to help stop misconceptions before the main differentiated activity.
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.
There is an extra challenge slide of an multiplication grid of negative numbers.
There is also a mixed challenge activity to be used with students once they have learnt how to add, subtract, multiply and divide negative numbers.
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)
