3 - 5 Geometric Thinking - Web Sites

  • A+ Math (ENC-012800) This is a drill-and-practice web site with a variety of problems and math games. Students can use this site on their own to practice computation skills through problems. Games like Concentration and Flashcards cover geometric shapes, money, and fractions along with addition, subtraction, multiplication, and division.

  • Elementary Problem of the Week: Stained Glass Window This enrichment problem from the Math Forum's Problems of the Week archive is for elementary students. Students must solve a puzzle to calculate area and perimeter. Solutions submitted by students who worked on this puzzle are highlighted here.

  • Helping Your Child Learn Math This resource was written for parents of children in kindergarten through fifth grade, but will also be useful for tutors. It includes a variety of activities to help children learn and apply mathematical concepts such as geometry, algebra, measurement, statistics, and probability in a useful and fun way. All of the activities relate math to everyday life and complement many of the math lessons that children are learning in school. Activities use materials that are easy to find.

  • 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.

  • 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 Tangrams This unit from the Math Forum web site explains tangrams and how to use these puzzles to introduce or reinforce geometrical concepts. The activities presented here use tangrams to compute the area of polygons and are designed for students in grades 4 through 6.

  • 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.
