26. Recognize and describe polygons (up to 8 sides), triangles, and quadrilaterals (rhombuses, rectangles, and squares) based on the number of sides and the presence or absence of square corners.

a. Draw examples of quadrilaterals that are and are not rhombuses, rectangles, and squares.

[MA2019] (5) 22 :

22. Classify quadrilaterals in a hierarchy based on properties.

In this video, learn about the specific properties of trapezoids. Trapezoids are special types of quadrilaterals that differ from squares, rectangles, and other parallelograms. In the accompanying classroom activity, students investigate what distinguishes this shape from parallelograms by building trapezoid models out of straw and tape.

22. Classify quadrilaterals in a hierarchy based on properties.

In this video, examine strategies to identify the properties of quadrilaterals—specifically, parallelograms. Students will compare and contrast squares, rectangles, and rhombuses, which are all parallelograms. In the accompanying classroom activity, students create posters identifying the properties of various quadrilaterals. They explore how these shapes compare and contrast and then analyze the ways that parallelograms distinguish themselves from other quadrilaterals.

22. Classify quadrilaterals in a hierarchy based on properties.

In this lesson, students observe symmetry, geometric shapes, and angles in two Early American dances, and then choreograph their own dance with symmetrical figures. Three options are provided in this lesson depending on the time in class.  In all three options, students will observe symmetry in dance.

[ARTS] DAN (2) 7 :

7) Demonstrate clear directional movement that changes body shape, facings, or pathway in space.

Examples: Identify symmetrical and asymmetrical body shapes and examine relationships between body parts.

Differentiate between circling and turning as two separate ways of continuous directional change.

[ARTS] DAN (3) 1 :

1) Improvise movements with a variety of self-identified prompts.

Examples: music/sound, text, objects, images, notation, observed dance experiences

[ARTS] DAN (3) 2 :

2) Select and demonstrate a movement solution for a given movement problem.

Example: Find a way to travel across the floor only on a low level.

[MA2019] (2) 25 :

25. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

a. Recognize and draw shapes having specified attributes.

Examples: a given number of angles or a given number of equal faces

a. Draw examples of quadrilaterals that are and are not rhombuses, rectangles, and squares.

Students will identify known shapes and describe their properties. They will create the shape with their body.  As a group, they will create a shape with all members. They will change groups and create another shape.

a. Draw examples of quadrilaterals that are and are not rhombuses, rectangles, and squares.

In this interactive activity, students will be led through steps to identify common types of quadrilaterals using their characteristics. There are teaching activities as well as practice activities available. A handout that reviews the quadrilaterals taught during the interactive is available to be printed. There is a karaoke song with printable lyrics that will help students learn and review the types of quadrilaterals. After utilizing this resource, the students can complete the short quiz to assess their understanding.

The CyberSquad must build a path to cross a stream of hot lava. They find a pile of triangle-shaped tiles which float in the lava and don't melt. Unfortunately, they run out of triangle tiles when they are only halfway across the stream of lava and must figure out what other tiles they can use to complete the path.

The CyberSquad must build a path to cross a stream of hot lava. They find a pile of triangle-shaped tiles which float in the lava and don’t melt. They work together to try to figure out how to create a path made of the triangle tiles that has no gaps and no overlaps.

The CyberSquad must build a raft to cross a river. The first raft they build floats, but there are gaps between the pieces of the raft that allow biting piranhas to jump through the holes. The CyberSquad uses their knowledge of tessellations to build a second raft out of squares that has no gaps or overlaps.
