Learning Targets

1. Mathematics: Students will be able to calculate the perimeter of various shapes using addition.
2. Music: Students will demonstrate rhythmic patterns with instruments that correspond to the calculated perimeters.
3. Collaboration: Students will work in pairs to complete hands-on activities.

Materials Needed

• Measuring tape or rulers (22)
• Various shapes cut out from cardstock (triangles, rectangles, pentagons, etc.) – at least 4 of each shape
• Tables for measuring and arranging shapes
• Instruments (shakers, drums, xylophones) for rhythmic activities
• Whiteboard and markers
• Worksheet for perimeter calculations and rhythm patterns

Lesson Breakdown

Introduction (5 Minutes)

1. Warm-Up Activity:
   • Ask students to share what they know about perimeter.
   • Briefly explain perimeter as the total distance around a shape.
2. Music Connection:
   • Introduce the idea that today, they will find perimeters and then create rhythms based on those measurements.

Hands-On Measurement Activity (10 Minutes)

1. Group Pairing:

   • Divide the class into pairs (11 pairs).
   • Provide each pair with a set of shapes.

2. Measuring for Perimeter:

   • Instruct pairs to measure the sides of the shapes using rulers.
   • Have them record the lengths of the sides on their worksheets.
   • Guide students to add the lengths of each side and write down the perimeter for each shape.

3. Differentiation:

   • For students who need additional support, provide a chart with visual examples of simple calculations.
   • Advanced learners can calculate the perimeters of irregular shapes or engage in mini-challenges to create new shapes and find those perimeters.

Rhythm Creation (10 Minutes)

1. Using Instruments:

   • Explain that each pair will now create a rhythm based on the perimeter they calculated, using their instruments.
   • Each inch or unit of perimeter will correspond to one beat.

2. Composition:

   • Allow students time to brainstorm rhythms that they can play on their instruments using the established beat.
   • Circulate to assist pairs with their rhythms and ensure their understanding of matching perimeter to rhythm.

Performance and Reflection (5 Minutes)

1. Showcase Rhythms:

   • Invite each pair to perform their rhythm for the class.
   • Encourage classmates to clap along or echo the rhythms.

2. Class Discussion:

   • Ask students to reflect on the following questions:
     • How did you find the perimeter of your shape?
     • How did you decide on your rhythm?
     • What did you like best about using music to understand perimeter?

Closing (5 Minutes)

• Recap the connection between mathematics and music.
• Reinforce that understanding perimeter can enhance creativity in areas like music.
• Hand out a brief quiz (homework) that reinforces perimeter concepts through a fun worksheet which incorporates drawing shapes and calculating perimeters.

Assessment

• Observational Assessment: Monitor student engagement and participation during activities.
• Worksheet: Evaluate the accuracy of the calculated perimeters.
• Performance: Assess creativity and understanding demonstrated in their rhythms.

Inclusion Practices

• Ensure that all students have access to materials.
• Pair students intentionally to balance different skill levels.
• Allow for alternative rhythmic expressions for students who might be less comfortable with performing.

This captivating lesson plan combines hands-on learning with creative expression, ensuring students not only grasp the mathematical concept of perimeter but also connect it to the joy of making music.
