1. Voki Lesson Plan
Teacher’s Name: Ms. Sunday Solomon
Lesson Title: The Discovery Lab/ values that vary
Description of Lesson:
Students have been introduced to the distance equation d=rt where d=distance, r= rate, and t=
time. The focus of this lesson is for students to be able to understand the relationships between
two variables, as well as gain a deeper understanding of why values vary. This lesson is an
extension of rates that change. A power point will be used to introduce key terms and concepts.
A graphic organizer goes along with the power point notes. Included in the power point are the
three different ways in which the formula can be used and interchanged (d=r/t, t= d/r and r = d/t).
After the power point, I will use a Voki to explain give the students their next task, the Discovery
Lab. The Discovery lab is the assessment for this lesson. Students will be split into 4 even
teams, each team is responsible for recording how long it takes each member to walk, jog, skip,
and run, 60 feet or 20 yards. The distance will always be 60 feet, which is known as the constant
variable since it does not change. The times will vary according to each individual, and the
rate(r) will be the unknown variable, because it is the one variable that they do not know.
Students will use the formula d=rt to solve for the (r) rate. This activity provides students with a
more tangible way to use the formula, instead of using practice problems out of the book.
Students are recording and interpreting data, and understanding how one value affects another
value in an equation.
Standard(s):
GA-GPS. M7A3: Students will understand relations and functions.
M7A3 (b): Represent, describe and analyze a functional relation from a table, graph, and/or
formula.
M7A3 (c): Describe the variation of two quantities.
2. Objectives:
Students will be able to represent tables, graphs, and formulas.
Students will be able to describe tables, graphs, and formulas.
Students will be able to interpret and explain how one variable affects the other.
Materials:
Data table
Stop Watch
Power Point and graphic organizer

Activities: The assessment for this lesson is the Discovery Lab. Students will use the
formula d=rt to complete the lab. The class will be split into groups and each group will be
responsible for recording the time it takes each team member to walk, jog, skip, and run 20
yards. The lab will take place outside where 20 yards will be sectioned off. Each group will
receive a stop watch and a data table. Once all group members have completed each task, the
students will return to the class to finish up the lab/assessment. The formula d=rt will now be
manipulated to find the new equation; we are now looking for rate and not distance. The new
formula will be r= d/t. Students will have to use some algebra skills to solve for r, in order to
complete the data table. Individually students will calculate the rate for each group member
using the new formula. There are 6 discussion and analyses questions. These questions will help
the students to organize and interpret the results of their data in more depth. Students are given
multiple ways to express their understanding of values that vary through the interpretation of
collected data.
