Symmetric and Congruent Figures
by Donna Thomas
West End, NC
Competency Goal: The learner will identify and make symmetric and congruent figures.
"C" Level Activities: Choose 5
1. Using the Sharpie Markers, color the butterfly transparency. Make sure
that the wing colors match when you fold the butterfly on the line of symmetry.
2. Cut out shapes that are congruent. Use the shapes to design another shape
that has a line of symmetry. Make a creative poster with the new shape.
Be sure to mark the line of symmetry. (See example in the Math Center.)
3. Create a list of 10 items from the room that are symmetrical. Indicate
where the lines of symmetry are.
4. Do pages 262 and 268. Do only the problems whose numbers you say when
you count by 4.
5. Using materials from the Creation Station (ex. play dough, yarn, buttons, etc.),
create congruent objects that have clear lines of symmetry.
6. Using "Kid Pix" on the computer create 10 pictures that demonstrate
congruency and symmetry.
7. Write in your Math Journal an explanation of congruency and symmetry.
Give examples of each.
"B" Level Activities: Choose 1
1. Using "Kid Pix" create a brochure explaining the concepts of
symmetry and congruency.
2. In your Math Journal, give examples of why we might need to keep
things congruent and/or symmetrical. In what professions would
this be really important? Be specific.
"A" Level Activities: Choose 1
1. Use the attribute blocks to explain congruency and symmetry to 1 of your teachers.
2.With a group or a partner, create a song, rap, or a poem that
will help people remember what these two terms mean. Be prepared to
share with the class.
