COURSE/LEVEL: 6th grade math
TOPIC: Mean and Median
GOAL OF LESSON: The goal of this lesson is to further develop students’ skills with finding the mean and median of sets of data and introduce them to box and whisker plots.
INSTRUCTIONAL OBJECTIVES: Students Will Be Able To (SWBAT):
NY State Standards for Mathematics:
NCTM Standards:
ISTE NETS-S Standards:
c. Use models and simulations to explore complex systems and issues.
d. Contribute to project teams to produce original works or solve problems.
a. Plan strategies to guide inquiry.
b. Locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of sources and media.
b. Plan and manage activities to develop a solution or complete a project.
c. Collect and analyze data to identify solutions and/or make informed decisions.
a. Understand and use technology systems.
b. Select and use applications effectively and productively.
MATERIALS:
RATIONALE: The NYS Mathematics Standards state that students should work in collaboration with others to solve problems, and they will be working in pairs to find means and medians during this lesson. Students will be modeling problems with the box and whisker plots using the online tool. They will be organizing their work as they find the means and medians of sets of data. Students will also learn and review the vocabulary words mean and median. Through the online tool, students will see how data points can be plotted on a simple number line and translated into a box and whisker plot; the online tool shows the median simultaneously on both representations. They will determine means and medians and read the graphs on the tool. The ISTE NETS-S state that students should use models and simulations, and the digital resource in this lesson is just that. Students will be using technology and using the application effectively and productively to visualize means and medians of sets of data. They will also be fulfilling standard two by working with others to solve problems.
PROCEDURES:
Introduction:
Mean: the quotient obtained when the sum of the numbers in a set is divided by the number of addends. (AKA: We add them all up and then divide by the number of things we added)
Median: The middle number of a set of numbers arranged in increasing or decreasing order; if there is no middle number, the median is the average of the two middle numbers.
Presentation:
Application:
ASSESSMENT: I will check each student’s work that they email me tonight (because they will finish the same sheet for homework).
ASSIGNMENT: Students will complete the even numbered problems on the sheet for homework and scan all of their work (from in class and at home) into their computers and email me their completed and scanned work as an attachment. Tell them to check their work using the tool from Illuminations that we used in class.
