There are six questions for each problem. Each time you give the correct response the questions will advance. Once you go through questions 1-6 you must reset the browser to refresh the page.
Try the following and record the answers on your answer key. Also, record how many boxes were cancelled out if any:
1. -7 + 3
2. 8 + (-6)
3. 3 + (-8)
4. -5 + 2
(If this were a real classroom I would use four-five problems of each type: (+)+(+), (+)+(-), (-)+(+), and (-)+(-).)
On your answer sheet record any patterns that you have noticed.
What rules can you create that will help you solve all integer addition problems?
(The questions above would be repeated with integer subtraction problems.)
