Circle and Square Wreath Symmetry

Lesson #10177
10177

Create a die-cut wreath with a circle or square opening by folding the paper before cutting.



Grade Level:
3-5, 6-8

WREATH FOLD: This technique can be used to create any circular or square wreath using virtually any die-cut shape. Wreaths can be used for anything from classroom decor to creative lessons and holiday gifts.

Create two-dimensional wreaths to identify lines of symmetry.

Supplies Used: Construction Paper, Glue, Pens, Scissors

The teacher will die-cut the materials for student use prior to the lesson.

Circular Wreath:

  1. Fold a 14" x 14" sheet of construction paper or patterned paper into three triangles (Figure A).
  2. Slide the closed point of the folded triangle (the center point if the paper is opened) down the center of the die, extending the point past the cutting edge of the Apple or Butterfly and then die-cut (Figure B).
  3. Open the circular wreath (see Video).
  4. Chalk, colored pencils, pens or crayons may be used to embellish the die-cut shape (see Main Photos).

Square Wreath:

  1. Fold a 12" x 12" sheet of construction paper or patterned paper into three triangles (see Video).
  2. Slide the closed point of the folded triangle (the center point if the paper is opened) along the left edge of the die, extending the point past the cutting edge of the Dinosaur and then die-cut (Figure C).
  3. Open the square wreath.
  4. Chalk, colored pencils, pens or crayons may be used to embellish the die-cut shape (see Main Photo).

4.G 3. Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

Math: Geometry

Pre-K-8: Instructional programs from Pre-Kindergarten through grade 12 should enable all students to use and apply transformations and use symmetry to analyze mathematical situations.

  • In Pre-Kindergarten through grade 2, all students should recognize and create shapes that have symmetry.
  • In grades 3-5, all students should identify and describe line and rotational symmetry in two- and three-dimensional shapes and designs.
  • In grades 6-8, all students should examine the congruence, similarity and line or rotational symmetry of objects using transformations.

Pre-K-8: Instructional programs from Pre-Kindergarten through grade 12 should enable all students to use visualization, spatial reasoning and geometric modeling to solve problems.

  • In Pre-Kindergarten through grade 2, all students should recognize and represent shapes from different perspectives.
  • In grades 3-5, all students should build and draw geometric objects.
  • In grades 6-8, all students should recognize and apply geometric ideas and relationships in areas outside the mathematics classroom, such as art, science and everyday life.
