• Practice order of operations with this game.

• Students can practice finding equivalent fractions with this FunBrain game.
• Use this funbrain game to practice addition, subtraction, multiplication, and division of fractions and whole numbers.
• Fraction Game Single player game
• Fraction Track game for two players (similar to Fraction Game)
• This applet allows you to model fractions and then shows the decimal and percent equivalent.
• This web site uses pattern blocks to create designs. Works really well with 3rd grade lessons 3-30 and 3-35.

• Find area of polygons by decomposing shapes at this web site.Learn the relationship between perimeter and area. A shape will be automatically generated with the perimeter that you choose.
• Calculate the area of this shape. You can choose only rectangular shapes or you can work with polygons that need to be decomposed to find their area.
• Calculate the area of a triangle drawn on a grid. Learn about areas of triangles and about the Cartesian coordinate system.
• A video about how to find the area of a triangle.
• A video about how to find the area of a trapezoid.

• Funbrain, several levels of difficulty; calculate the perimeter and/or area; how to find area and perimeter and example are also included on the game page
• .Find the area and perimeter of rectangles. Begins with a mini-lesson and then students manipulate a ruler to measure rectangles and then calculate the perimeter and area. This is a self-checking activity.
• A movie demonstrating the difference between area and perimeter; also demonstrates that shapes with the same area can have a different perimeter.
• This site helps students find area and perimeter of non-rectangular shapes.
• This is a mini-lesson on area and perimeter; students learn how to find perimeter and then get to try a few problems on their own.
• Use this applet to create rectangles of various perimeters and area.

• Students match geometric terms with pictures at this site to uncover a hidden picture.
• Students compete against the clock to match geometric terms with pictures at this site to play MATHO.

• Students can practice their measuring skills in centimeters or inches with this Funbrain game.

• Adam Ant demonstrates how to find the perimeter of a rectangle and students fill in the answer before progressing to the next problem.
• Students count units to determine the perimeter; shapes are irregular and students can choose the area.
• Practice finding the perimeter of squares given the length of one side.
• Practice finding the perimeter of rectangles given the length and width.

• Students take a quiz identifying types of angles as this web site.
• This web site offers a tutorial on angles and how to use a protractor. Click on skip intro and then choose lesson 16. The site has a virtual protractor that can be used to measure angles and create angles given in the tutorial (this is a very nicely done web site).

• Students practice classifying triangles by angle measure at this web site.
• Students practice classifying triangles by length of side at this web site.
• This site has a tutorial and a quiz about triangles and how to classify triangles by length of sides. Choose the lessons button and then click on triangles.
  

• Check out this web site for flag symmetry.
  
• This web site has some neat symmetry illustrations and links. Be sure to check it out before using it with students!
  

• Students practice stopping a clock at a specific time with this web site (evaluation written across the screen may be a bit distracting).
• This is a great web site for letting students move hands of the clock to a specific time.
• Students work with elapsed time here.
