8 - 9 Geometric Thinking - Web Sites
- Area Flashcards Practice calculating the area of geometric shapes including squares, circles, and trapezoids. This online game keeps track of your score and explains the correct answer when you miss one.
- Illuminations : principles and standards for school mathematics (ENC-016955)
Created by the National Council of Teachers of Mathematics (NCTM), this site provides online information and activities to support and demonstrate how the new mathematical standards, PRINCIPLES AND STANDARDS FOR SCHOOL MATHEMATICS (PSSM), can be applied in the classroom. A section called i-Math features ready to use online interactive mathematical investigations for students; these include teacher notes, discussion questions, and connections to pages of the PSSM. Other sections of the ILLUMINATIONS web site offer video vignettes of classroom activities to promote discussion; Internet resources offering mathematical background information and support for the implementation of the PSSM; lesson plans for each grade band; and a searchable interactive version of the updated NCTM standards.
- Math Forum This site is a center for teachers, students, researchers, parents, educators, and all who have an interest in mathematics education. The Math Forum collects Internet and teacher-initiated mathematics resources and organizes them by subject so that these resources can be readily accessed. A favorite Math Forum feature, Problems of the Week, provide a creative mathematical challenge for students that can be used in the classroom or at home. New problems are offered each week for elementary, middle school, algebra, geometry, and trigonometry and calculus students.
- Math Lessons That Are Fun, Fun, Fun!! This site includes 15 mathematics lessons ranging from math puzzles to algebra and geometry. Sample lessons include Calendar Fun in which students use a simple algebraic formula to determine which four days add up to a given sum. In The Hot Tub, students are asked to interpret data from a graph to tell a story.
- Mrs. Glosser's Math Goodies : interactive math lessons with a problem-solving approach! (ENC-014903) This web site offers 32 problem-solving lessons for grades 5 to 8. Math topics include integers, percent, and circumference and area of circles. The lessons are organized into volumes of related lessons and can be down loaded as shareware and used offline. Each individual lesson is designed as an independent learning module or as a supplement to other math instruction and includes three or more detailed examples.
- Shape Surveyor This goal of this online game is to uncover an archeological treasure. You can remove the puzzle pieces to discover your treasure by calculating the area or perimeter of the rectangles presented. For each problem you get correct, you uncover a piece of the archeological puzzle. Set the game to practice perimeter at the easy level for computation practice.
- Tom Scavo's Geoboards in the Classroom This unit from the Math Forum web site explains geoboards and how to use them to explore the concepts of length and area of two-dimensional geometric figures. With a geoboard, a student can see the area of a rectangle and will readily count the square units making up such a geometric figure.
- A Tour of Measurement These web pages provide lessons and materials on measurement topics for elementary, middle, and high school students. Tutors might review these pages to catch up on their own content knowledge. The site also presents questions and answers about measurement from the Math Forum's Ask Dr. Math and describes software that can be used to teach and learn measurement.
