Howdy,
...my mother-in-law teaches middle school math, and I have been taking
her lessons and rewriting them so that they
use LEGOs. The following is an example...enjoy!

Title: Making LEGO Line Plots
Objective:
Students will create a line plot using a frequency table recording the
number of
LEGO® 2x4 bricks in a 2 liter container.
Key Vocabulary:
Frequency Table, Line Plot, Range
Materials:
Access to a variety of LEGO® elements (such as found in an AOE Lab).
PREPERATION: Be familiar with AOE Lab and LEGO materials. Be familiar
with
a digital camera so that student creations may be documented. Prepare
a series of 2 liter containers ( cut open pop bottles work fine )
filled with 2x4 bricks. Have graph paper available.
Discussion:
The instructor will ask students to guess the number of 2x4 bricks in a
2 liter container.
To answer this question, data about how many bricks should be
incorporated into a
frequency table. A frequency table shows the number of times each type
of answer occurs.
"Line plots" are often used to visualize data. A line plot displays the
data using
a number line and are useful in identifying the range ( the difference
between
the greatest and the least values in a set of numerical data ).
Activity 1:
The instructor will ask the class to identify the number of LEGO bricks
in a
2 liter container. Students will paired off and count the number of
bricks in
their team's container. Each team is required to record the
the number and then to organize the data into a frequency table.
Activity 2:
Students will organize their frequency table data into line plots on
graph paper.
Students will write a title describing the data ( "number of bricks in a
2 liter
container" ). Each team will draw a number line with the team number
below it, and record each team's data.
Activity 3:
Students will identify the range in their class line plot.
Activity 4:
Students will be asked to write a short paragraph defining "range" and
its importance.
Special Notes: Have fun with this one!
