Give Me a Hand or Leaf Me Alone - TI-83

Activity Overview

In this activity, students find the surface area of geometric shapes cut from card paper and relate it to its mass. They use this data to find the surface area of irregularly shaped objects.

Before the Activity

Set up the calculator for data collection using the procedure described in the attached Appendix PDF file

See the attached PDF file for detailed instructions for this activity

Print pages 57 - 65 from the attached PDF file for your class

During the Activity

Distribute the pages to your class.

Follow the Activity procedures:

Use card stock paper and cut out squares with sides of different lengths

Measure the mass of the different square cut outs

Enter the mass and area of the squares data as lists

Graph a scatter plot and find a linear regression equation for the data

Graph the best fit line

Calculate the slope

Cut out tracings of a hand and a leaf on card stock paper

Find the mass of the cut-outs

Find the surface area of the hand and the leaf

After the Activity

Students will complete the Data Collection and Analysis page and answer questions listed on it.

Review student results:

As a class, discuss questions that appeared to be more challenging

Re-teach concepts as necessary
