Maker Challenge: Crafting an A.P. with Recyclable Materials

Students will create a sequence of items using recyclable materials to illustrate an Arithmetic Progression. Each piece will symbolize a term of the A.P., while the spacing between them will showcase the common difference.

1. Divide students into groups of 4 to 5 members.

2. Provide each group with recyclable materials (bottles, caps, boxes, etc.).

3. Instruct each group to define an Arithmetic Progression with a particular common difference (for instance, a common difference of 2).

4. Students should assemble a sequence of items representing the first 10 terms of the defined A.P.

5. Groups must arrange the objects so that the gaps between them align with the specified common difference.

6. Each group should showcase their creation to the class, detailing their chosen common difference and how they determined the terms of the A.P.

Apply the concept of Arithmetic Progression in a practical and collective manner, fostering teamwork and problem-solving abilities.
