This SmartBoard presentation will assist in teaching students who need more support with understanding how to add and subtract positive and negative numbers.
Some students are able to memorize the rules or use a number line to assist them. Others need a visual that they can manipulate.
This provides a manipulative and also gives students an opportunity to visualize why a negative that is being subtracted, is actually the same as adding a positive.
I used this as an intervention to re-teach in a small group, the students who were unable to demonstrate mastery on an "Exit Slip".
Other uses include...
- Introduce adding and subtracting integers to the whole class
- Math Center
- Co-teaching: One teacher introduces the concept using the Smart Board presentation, the other uses a number line or explains the "rules" for adding and subtracting integers.
There is also an "Exit Slip" on the last slide to check for students understanding after the lesson.
