Introducing the Activity

Create simple dances in which the dancer’s parts rotate at: 1) 90 degrees; 2) acute angle measurements; 3) obtuse angle measurements. Then create dances with angle pairs (i.e., complementary and supplementary angles). Use what you learn to create a final dance with different angle types. What mood or effect do you achieve from each dance?

To Do

Part 1: Angle Type Exploration (20-40 minutes)

Have students try three types of angle dance moves:

• Right Angles: Create a simple dance in which all the parts only rotate at +90 or -90 degree angles. Save the dance to share with the class later. What are some things you notice about your dancer as its parts only rotate 90 degrees? Did anything surprise you?

• Acute and Obtuse Angles: Make a simple dancer whose parts only rotate with acute angle measurements. Then create a simple dance where all the parts rotate with obtuse angle measurements. Save each of these as projects. When you animate the two dances, what are some things you notice?

• Angle Pairs: Explore angle pairs (i.e., complementary and supplementary angles). Create a simple dance where pairs of parts have these relationships. For example, one part will move 50 degrees and the part right next to it will move 130 degrees. Ask: When you animate these parts, what kind of effect do you get? Pleasing? Unrealistic?

• Vertical Angles: Repeat using two different parts to create a simple dance with vertical angles that rotate with equal measure but opposite each other.

Part 2: Dance with Angle Combos to Create a Mood (20 minutes). Based on explorations from the part 1, have students:

• Create a new dance by selecting different angle types to achieve a certain mood or effect.
• Describe what types of angles achieve certain effects, such as graceful, subtle, jerky movements, etc.
• Be sure students use mathematical language to describe the angular moves of their dance and the mood they create.

Discussion

While students are creating their final dance moves, it’s important to prompt their thinking around the following areas:

• Which types of angles did you enjoy using the most?
• What did you notice when you animated dances using the different angles?
• Which angle-based dance moves looked the most realistic?
• Which angle-based dance moves created the mood you were after? Why?

Listen for:

• Acute angles seem more subtle because they are moving less degrees.
• Because obtuse angles have greater degrees, they create more obvious movements.
• Vertical angles look opposite and equal.

Extensions and Inquiring Further

To help solidify what differentiates the angle types, have students identify the angle types incorporated into their classmates’ dances by viewing their animations without angle measurements turned on. Are they able to guess what angle types the dance contained? How accurate are they?

Part 1: Angle Type Exploration

Explore Angle Types:

• Right Angles: Create a simple dance in which all the parts only rotate at +90 or -90 degree angles. Save your dance as a project to share with your classmates and teacher later. What are some things you notice about your dancer as its parts can only rotate 90 degrees? Did anything surprise you?
• Acute Angles: Now make a simple dancer whose parts only rotate with acute angle measurements. Also create a simple dance where all the parts rotate with obtuse angle measurements. When you animate the two dances, what are some things you notice?
• Angle Pairs: Let’s explore the angle pairs or complementary and supplementary angles. Create a simple dance where pairs of parts have these relationships. For example, one part will move 50 degrees and another part next to it will move 130 degrees. When you animate these parts, does anything stand out for you? How do these paired angles affect the dance?
• Vertical Angles: Finally, create a simple dance with vertical angles that rotate with equal measure but opposite each other. When you animate these parts, what stands out the most?

Part 1: Angle Type Exploration

Dance Moves With Angle Pairs

Let’s explore the angle pairs of complementary and supplementary angles. Create a simple dance where pairs of parts have these relationships. For example, one part will move 50 degrees and the part right next to it will move 130 degrees.

1. When you animate these parts, does anything stand out for you? How do these paired angles affect the dance?

2. Sketch your dance below. Be sure to include the angle measurements.

Part 2: Dance With Angle Combos to Create a Mood

Based on your experience playing with these angles, create a dance that uses a combination of angles types.

1. Sketch your dance below. Be sure to include the angle measurements.

2. Describe the angle types that you used and why. Were you able to achieve the mood you set out to create?

App Features

Begin by entering Make Some Moves. In Build mode, students will:

• Take Pictures
• Trace and cut out parts of your photo that you want to animate
• Add graphic or musical elements below:

In Animate mode, students will use the:

Graph Controllers. Choreo Graph uses keyframes much like other movie editing software. At each point in the keyframe, the student can manipulate how each part of the animation rotates. Each node on the line graphs below the stage represents the position of that part at a specific time. Stretch the points up and down to set the degrees of rotation. The steeper the line on the graph, the faster the part moves.

Toggle on math tools to notice:

Degrees each part has rotated
