This is an awesome math lab. It not only allows students to experience some of the really neat features of their TI-83 or TI-84 graphing calculator, but also allows students to:
-formulate a prediction equation
-determine a line of best fit (linear regression)
-write the equation of a line
-analyze real world data
-students come to their own conclusion based on their processing of data
-students compare their own answers using line of best fit with the graphing calculator's "answers"
Perfect for the block (1 class) or regular class (2 classes). Lab takes approximately 90 minutes. 30-45 minutes is teacher led. It is recommended that teacher walk students through the lab using your home state. Then students work in pairs on another state's data. Some students can then do lab in 30-40 minutes whereas others will need 60 minutes or so. Actual census data (provided) is linear for 42 states and the United States itself. Extension activities include student's creating posters of their results for classroom display and/or computer lab research of census data or a quest for more linear data to analyze.
This lab has worked for me mostly at the algebra 2 level with students of various levels (honors, regular and basic) and is good for algebra 1 too (but access to graphing calculators is more difficult sometimes).
Purchase includes 7 pages:
Page 1 - (available on preview) gives objectives and detailed directions of lab.
Page 2 - (available on preview) gives the student worksheet where student works through data manually and then again with the graphing calculator.
Page 3 - step by step or key by key instructions for the graphing calculator provided.
Page 4 - Questions provided for student response/analysis. And grading rubric for easy on the spot grading of math lab.
Page 5-7 - Real world census data provided for 42 states plus the United States country itself. Decades 1930, 1960, 1980, 1990 and 2000 provided. Students then predict 2010 data (which should come out by next year) and beyond. (2 pages are the original chart of data retyped for clarity on a word doc.)
This is a very user friendly assignment. It's turn-key ready. Students love this. It's such a change of pace and the students are interacting with real data using all the skills they recently learned/reviewed in class. This is a must have lesson. You'll be quite glad you purchased this for years to come.
