Overview:
This podcast is intended to accompany the lesson "Geometric Quilts." It is intended to be shown to the class between the design and creation segments of the project. Students will get tips to putting their quilt together properly and will get to see other students' completed quilts. Students will also see some quilts that were not properly constructed in hopes that they will not make the same mistakes.
Length: 3:00
Aligned to the following ALEX lesson plan:

MA2015 (8)  16. Verify experimentally the properties of rotations, reflections, and translations: [8G1] a. Lines are taken to lines, and line segments are taken to line segments of the same length. [8G1a] b. Angles are taken to angles of the same measure. [8G1b] c. Parallel lines are taken to parallel lines. [8G1c]   MA2015 (8)  17. Understand that a twodimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. [8G2]   MA2015 (8)  18. Describe the effect of dilations, translations, rotations, and reflections on twodimensional figures using coordinates. [8G3]   MA2015 (912) Geometry  3. Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself. [GCO3]   MA2015 (912) Geometry  34. Determine areas and perimeters of regular polygons, including inscribed or circumscribed polygons, given the coordinates of vertices or other characteristics. (Alabama)  
National/Other Standards: NCTM Standard: Apply transformations and use symmetry to analyze mathematical situations. • understand and represent translations, reflections, rotations, and dilations of objects in the plane by using sketches, coordinates, vectors, function notation, and matrices; • use various representations to help understand the effects of simple transformations and their compositions.
