Negative Numbers

1. Make Observations & Ask Questions
1. Think: What do you notice about this graph? What questions do you have? (1 min)
2. Pair: Share your observations and questions with a partner. (1 min)
3. Share: Be ready to share 1-2 of your pair's observations with the class (2 min).
2. Define a Problem or Form a Hypothesis
1. Think: What do you think we have to know in order to be able to create and understand graphs like this? (1 min)
2. Pair: Share your hypothesis with a partner (1 min).
3. Share: Be ready to share your hypotheses with the class ( 2 min).
3. Develop a Plan
1. One of the topics we'll need to be able to understand and use in order to graph is negative numbers.
2. Draw a positive/negative sheet. I'll give you a pile of counters; make sure you have around 15-18 per person.
4. Conduct & Analyze an Experiment
1. I'll demonstrate how to use the counters and have you practice some problems about debt and the weather.
2. We'll then write number lines and discuss how to use them for adding and subtracting negative numbers.
3. We'll review how to do multiplication and division with negative numbers.
5. Communicate Results & Improve
1. Take the negative computation formative assessment to help us know how to help you improve.
