Mini marshmallows
Toothpicks
Shape templates (optional, for guidance)
Labels and markers (optional)
Chart paper or construction paper (for displaying shapes)
Introduction (5 minutes):
Discuss basic 2D geometric shapes such as squares, triangles, rectangles, and hexagons.
Explain the activity: students will use marshmallows and toothpicks to construct these shapes.
Demonstration (5 minutes):
Show students how to connect marshmallows and toothpicks to form a simple shape, such as a triangle.
Explain that the marshmallows will act as the vertices (corners) and the toothpicks will act as the edges (sides) of the shapes.
Constructing Shapes (15 minutes):
Distribute marshmallows and toothpicks to each student or group of students.
Provide shape templates if desired, or encourage students to create the shapes based on their knowledge.
Have students start with simpler shapes like triangles and squares, then progress to more complex shapes like pentagons and hexagons.
Shape Identification and Discussion (10 minutes):
After constructing the shapes, have students identify and name each shape.
Discuss the properties of each shape, such as the number of sides and vertices.
Creative Play and Extension (10 minutes):
Encourage students to use their marshmallows and toothpicks to create their own designs or more complex shapes.
Allow students to work in pairs or small groups to build larger shapes or combine shapes to form new ones.
Display and Sharing (10 minutes):
Have students place their completed shapes on chart paper or construction paper for display.
Allow students to share their creations with the class, explaining how they constructed each shape.
Reflection and Learning Points (5 minutes):
Reflect on the activity by discussing what students learned about shapes and the process of building them.
Highlight the importance of teamwork and creativity in constructing shapes.
Conclusion:
Emphasize the importance of recognizing and understanding 2D shapes in everyday life.
Celebrate the students’ creativity and efforts in constructing their shapes with marshmallows and toothpicks.
