 * 1) Open Kidspiration 3. [[image:KidspirationIcon.jpg]]
 * 2) Click on MATH VIEW. [[image:Kids3-MathView.jpg width="48" height="56"]]
 * 3) Click on PATTERN BLOCKS.[[image:Kids3-PatternBlocks.jpg width="73" height="47"]]
 * 4) Click on the NAME button [[image:Kids3-NameButton.jpg]], type their name, and click OK.
 * 5) Click and drag a text box [[image:Kids3-TextBoxButton.jpg width="72" height="39"]] to the top right of the screen, then type "have line symmetry."
 * 6) Click the GO TO PAGE button [[image:Kids3-GoToPageButton.png width="65" height="45"]], click ADD [[image:Kid3-AddStep.jpg width="60" height="46"]], and then PATTERN BLOCKS [[image:Kids3-PatternBlocks.jpg width="73" height="47"]].
 * 7) Click and drag a text box [[image:Kids3-TextBoxButton.jpg width="72" height="39"]] to the top right of the screen, then type "have rotational symmetry."
 * 8) Click and drag a square from the left to the workspace
 * 9) Click and drag a line to drop over the square to show a line of symmetry. If there is more than one line of symmetry for the shape, add more lines and add it to the ROTATIONAL symmetry page. If there is only one line of symmetry, add it to the LINE symmetry page.
 * 10) Type the shape's name in the text box adding correct punctuation.
 * 11) Repeat for all shapes- triangle, hexagon, trapezoid, and rhombus. Adjust any shape descriptions to accurately describe the shape such as equilateral triangle vs. isosceles triangle.
 * 12) Click FILE and PRINT. (Click on the COPIES & PAGES drop-down menu to change to LAYOUT. Change the PAGES PER SHEET from 1 to 2.) Then, click PRINT.
