6th
grade Mathematics – Geometry Objective: Students will apply their knowledge of polygons into an
organized web. Then,
students will classify pictures of triangles and quadrilaterals into
appropriate categories. New
York State Standard: Standard
3: Mathematics – Students will understand mathematics and become
mathematically confident by communicating and reasoning mathematically,
and solving problems through the integrated study of number systems,
geometry, algebra, data analysis, and trigonometry. Skills: 1.
Organization
and inquiry 2.
Integrating
information using technology 3.
Classifying Materials
Needed: 1.
Inspiration 2.
Digital
Camera 3.
Class
notes 4.
Internet
website: http:www.math.com Preparation: 1.
Ask
students to search their home for examples of triangles and
quadrilaterals found outside the classroom. 2.
Spend
time with class discussing examples and having the students take notes
on two different types of polygons: triangles and quadrilaterals. 3.
Take
a tour around the building with the students to discover examples of
triangles and quadrilaterals. Use
a digital camera to photograph them, (in addition, the teacher may opt
to take pictures in the community.
The photographs provided were taken in San Francisco). On
the computer: 1.
Have
students complete the template provided using their notes, their
knowledge of polygons and the internet website: http:www.math.com. 2.
Then
have students classify the pictures they generated from their adventure
around the school into their appropriate categories.
Be sure to discuss with the students that some pictures can fit
into more than one category. Follow-up: 1. Have students share and compare their diagrams in small groups and explain how they classified each shape and why. Students should recognize things such as a right triangle could be classified as a right triangle or possibly a scalene triangle and a rhombus could be classified as a rhombus or a parallelogram.
