This is a Smartboard lesson teaches students how to analyze data in an input/output table. Students will work to complete the tables and then try to figure out the rule for each. On some pages the rule is given and students need to fill in the missing input or the missing output numbers. Some pages have a completed table and students need to figure out the rule. This is a great lesson for a beginner algebra unit. This lesson goes well before or after my balances and scales lesson. The preview file has thumbnail shots of many of the pages from this lesson.
