What
is an Online Learning Activity?
Online Learning Activities are activities that are completed
while on the computer. These activities include games, interactive
tools, web quests, research and discovery learning activities.
For proper viewing, some of these activities may require
plugins (Flash, Quicktime, etc). You may require notebooks
and pencils to record information as you work through the
activities.
Online
Learning Activities for Length
 Practicing
Perimeter
(GM 44): This activity uses an interactive tool to give
students practice determining the perimeter of various
shapes. Students are able to check their work as they
go along.
 Pythagorean
Theorem
(GM 52): Student will use a Pythagorean Explorer to create
various right triangles with 1 unknown sidelength. They
are asked to calculate the length of one unknown side
using Pythagorean's Theorem. A virtual calculator is provided
to assist with calculations.
 Using
a Virtual Geoboard to Explore Length and Area
(GM 44, GM 48, GM 51): Students are required to use the
virtual geoboard to create various shapes. Using the geoboard
to get some of the required measurements, students are
to use formulas to determine final measurements (length,
area, and perimeter).
 Magic
Ruler: This activity gives students practice
measuring objects using a virtual drag and drop ruler.
This requires the flash plug in to work properly. Examines
polygons and circles.
 Perimeter
of Polygons :
Understand the concept of perimeter , find the perimeter
of various polygons and regular polygons, and express
the answer using the proper units. (GM 48)
