Reads and interprets data in charts, tables, and plots (e.g., stem-and-leaf, box-and-whiskers, scatter). Organizes and displays data using tables, graphs (e.g., line, circle, bar), frequency distributions, and plots (e.g., stem-and-leaf, box-and-whiskers, scatter). Knows that an expression is a mathematical statement using numbers and symbols to represent relationships and real-world situations (e.g., equations and inequalities with or without variables).

Objective(s)

Students will:

• become familiar with hand geometry using measurement skills and spreadsheets

Time Required

90 Minutes or two 45 minute lessons

Pre-Requisite Skills

Measuring with a ruler to centimeters and problem solving skills

21st Century Tools (Technology Tools)

The students may use EXCEL to compile the data from the hand measurements.

Instructional Materials

Centimeter Rulers, HANDS DOWN, HAND MEASURMENT OVERHEAD, HAND MEASURMENT OVERHEAD EX, Computer with EXCEL

Procedure

DAY ONE

1. Introduce the concept of Hand Geometry by sharing pictures of devices from a Google Search and discuss the uses for security
2. Discuss uses of Hand Geometry for saftey and security
3. Review over the  HANDS DOWN worksheet and demo the measurements
4. Separate the class into heterogenous groups students work collaboratively to complete the HANDS DOWN worksheet

DAY TWO

1. Review Hand Geometry and it's uses
2. Using HAND MEASURMENT OVERHEAD to demonstrate how to develope a code for your hand meausrements and turn it into a code using variables (For example of Overhead see HAND MEASURMENT OVERHEAD EX)
3. Allow each group to develope a code (Keep it confidential)
4. Each group will create a data table utilizing EXCEL on the computer based on thier code of each of group members data from the HAND DOWN worksheet
5. After all groups are complete, switch data tables and HANDS DOWN worksheets to crack the codes

Differentiated Instruction

Heterogenous groupings
Allow students to create the Data table on paper instead of EXCEL
Allow students to check thier measuring with peers

21st Century Assessment/Evaluation

This activity contains an exploration of the Biometric and accuracy is not necessary.  Utilize the RUBRIC to assess performance of the groups.
