Shapes and Attributes

• What’s In My Brain: Pentagon vs Pentagon

  Students will analyze examples and non-examples to deduce the topic: regular and irregular polygons.

  Show 3 Steps

  1. First, students get a set of items categorized in two groups.

  2. Students decide where to place three mystery items into groups A and B based on their own reasoning and discussion.

  3. Finally, I reveal the topic: regular vs irregular polygons.

• Grouping Shapes by Parallel and Perpendicular Sides

  Students will spot the number of parallel and perpendicular lines in shapes and then form groups of shapes.

  Show 3 Steps

  1. First, students will identify the number of sets of parallel and perpendicular sides in various shapes.

  2. Next, they create three or four groups based on their findings in step one.

  3. Students identify and categorize shapes based on parallel and perpendicular sides, adding examples to each group for clarity.

• What’s In My Brain: Trapezoids or Not?

  Students will analyze the shapes and determine the pattern: we’ve got trapezoids!

  Show 3 Steps

  1. First, students guess the topic by looking at examples and non-examples, and then discuss their ideas with peers.

  2. Next, students will decide which of three items are examples and which are non-examples of the given topic.

  3. Finally, students identified and classified three shapes based on their parallel sides to distinguish between trapezoids and non-examples.

• Grouping Quadrilaterals In A Hierarchy

  Students analyze the similarities and differences of several quadrilaterals.

  Show 3 Steps

  1. Students choose a quadrilateral, identify which one is most and least similar, and explain their reasoning for each choice.

  2. Students group quadrilaterals by analyzing their angles and sides, identifying similarities and differences based on specific characteristics.

  3. Students develop a hierarchy using the criteria from the previous video.

• Fractals: Sierpinski’s Triangle

  Students divide equilateral triangles over and over to create a Sierpinski Triangle.

  Show 3 Steps

  1. Students learn to create their own Sierpinski Triangle by starting with an equilateral triangle.

  2. Then, they create Sierpinski Carpets by starting with a square.

  3. Students design three-dimensional versions of Sierpiński fractals using LEGO, Minecraft, or other materials.

• Fractals: Koch Snowflake

  Students will create a fractal known as The Koch Snowflake.

  Show 3 Steps

  1. Students first create a Koch Curve – a simplified version of the Koch Snowflake.

  2. They’ll take their curve from step 1 and extend it to become a snowflake.

  3. Finally, students will create new versions of the Koch Snowflake by experimenting with different starting shapes.
