7th grade math poster project

7th graders are making a poster or presentation showing how to work with negative numbers. The slideshow shown in class is below.

Students' posters should include text that shows how to work with negative numbers in 1 of 5 situations. Students can copy and paste one of these for a title of their poster: 

1. Adding with different signs 

2. Adding with the same sign 

3. Subtracting with negative numbers 

4. Multiplying with negative numbers 

5. Dividing with negative numbers 

Each poster should include a rule, algorithm, or visual explanation. I would like to see students use their own words to explain, but these statements can be used. Here are some examples:

• Adding 
• Same sign: add, then keep the sign 
• Different sign subtract, then use the sign of the larger number
• Take the absolute value of each number, subtract one number from the other, use the sign from the larger number
• Adding a negative number is the same as subtracting a positive
• Subtracting
• Change to addition of the opposite value then, follow the addition rules
• Subtracting a negative number is the same as adding a positive
• Multiplying
• If the signs are different, the answer is negative 
• If the signs are the same, the answer is positive
• Dividing
• If the signs are different, the answer is negative 
• If the signs are the same, the answer is positive 

Students will come up with their own number sentences and examples.
