This powerpoint is interactive. Students watch a few examples with visuals, then take notes, try 5 problems on their own, and check their answers. When prompted to tell how they are doing, students click on pictures to take them to the appropriate slide - review or move on. There are 3 levels of practice for each type of addition (same & different signs) and answers are provided. Two worksheets go with this along . Download Adding integers (different signs) and Adding integers (same signs) and their answer keys from my page. The powerpoint instructs students when to work on which worksheet. This is great for whole group instruction, small group instruction, and independent or partner work. As there is no sound, this can be a great resource for students with auditory processing disorders. No explanation is needed for this powerpoint. It is also excellent to catch up students who were absent and could be a resource for parents.
