Last time, we added positive and negative integers using black and red squares. Now we will show the red squares first and students see that the rules are the same.
In yet another video focusing on addition and subtraction of positive and negative integers, we introduce a number line as a tool to help organize our thinking. The video shown at the top of the post has the entire visual progression. However, the video is chunked into smaller pieces...
Let's continue exploring integer addition, but this time we will progress from using colour alone to represent the opposite signs of positive and negative values and explicitly write out these expressions and equations mathematically!
In this Math Is Visual video animation and visual prompts, we will explore early addition and subtraction question structures through concrete and visual representations! Learn about joining, separating, part-part whole relationships and comparing relationships.
