3. Geometry (G)
Fifth Grade
- "Know the Meaning of Angles, and Solve Problems"
- About Symmetry and Pattern (Field Patterns) - This site is appropriate for upper elementary grades. Examples of shapes and letters are shown and how they create patterns and how rotating the letters create a change in the pattern.
- Alphabet Geometry-Acute Angles - This site uses alphabet letters to show how to classify acute angles.
- Alphabet Geometry-Obtuse Angles - Students learn to classify obtuse angles using letters from the alphabet.
- Alphabet Geometry-Right Angles - Right angles are explained by showing letters of the alphabet.
- Alphabet Geometry-Vertical Angles - Vertical and angles on a straight line are explained with the letter x. Excellent visuals.
- Angles - This space game gives students a chance to estimate angles from 0-180 degrees.
- Angle Tangle - A two player angle game of drawing and estimating. Players subtract the difference for a score: low score wins!
- Animal Weigh In - This site is recommended for 4th grade and up, may even be used with middle school. The site allows students to compare and estimate the weight of animals and gives them several chances before it helps them out. A balance scale activity which has the student drag weights to match the unit given.
- Banana Hunt - Get as many bananas as you can by guessing the degrees of the angles. Students will get immediate feed back and become familiar with degrees of angles in this fun interactive game. Careful, it could be addictive!
- Bathroom Tiles - This interactive site allows students the chance to practice estimating measurements of angles.
- Coordinate Graphing - The student will transform a figure on a coordinate grid. The figure may be flipped, rotated, translated, and turned. Grade level 5 and up.
- Finding the Third Angle - This activity helps students practice finding the missing angle of a triangle. A short explanation is also given.
- Funbrain Change Maker Game - Outstanding - Interactive game which asks to give the amount of coins that represent change for $1.00 or $100.00. Graphics are lifelike. Grades 2-4.
- Interactive Geometry - Features several applets for discovering the basic principles of geometry. Students can manipulate figures such as polygons, angles, triangles, and parallel lines to learn about postulates and theorems.
- Judge and Jury - Students explore non-standard units and compare relative sizes of "steps" in this activity. They determine how the size of each type of step is important to how many steps it takes to measure an object.
- Kidport 5th grade Mathematics - Measuring Angles. Students will be able to move a protractor to an angle and find the appropriate measurement. Immediate feedback is given. Great for individual learning.
- Math Playground Measuring Angles with a Protractor - Interactive practice using a protractor to measure angles. The site gives 10 angles for students to measure, fill in the measurement and check the answer. The protractor is already lined up with the vertex of each angle, students are to rotate the protractor into the proper position before measuring. There is a one degree of error so students need to measure and remeasure to ensure a correct answer. Good for 4th grade practice, is a 5th grade GLCE.
- Protractors - Excellent site for teachers to demonstrate using a protractor. This is also an excellent site for students to practice using and learning how to use a protractor. Students will make and measure angles with immediate feedback. After practicing with this on-line protractors students will be able to use the actual protractors with ease.
- Study the Shapes - Outstanding - Grades 3 and up. This interactive site allows students to explore and manipulate geometric shapes. Students are encouraged to compare and describe shapes according to their attributes.
- The Mysterious Tangram - Outstanding - This is a very student friendly and fun site. Students build shapes by turning, flipping, and combining others to fill patterns. The site gives clues and encourages children by using positive sayings. Good for children 1st grade through 6th.
- "Solve Problems About Geometric Shapes"
- Animal Weigh In - This site is recommended for 4th grade and up, may even be used with middle school. The site allows students to compare and estimate the weight of animals and gives them several chances before it helps them out. A balance scale activity which has the student drag weights to match the unit given.
