Activity Suggestions
It is recommended that only one of the suggested activities be carried out
Activity 1 - Digital Influencers: Calculating with Sponsorships
> Duration: 60 to 70 minutes
- Objective: Apply the decimal representation of rational numbers in a contextualized and practical scenario, promoting collaboration and creativity among the students.
- Description: Students will be divided into groups, and each group will be responsible for creating a fictional profile of a digital influencer on Instagram. The objective is to simulate the management of sponsorships involving decimal values, using tenths and hundredths. Each group will choose products to advertise and calculate earnings based on the number of posts and the amount paid per post.
- Instructions:
-
Divide students into groups of no more than 5 people.
-
Each group should create a fictional digital influencer profile on Instagram using a sheet of paper or a digital presentation (PowerPoint, Google Slides).
-
Choose fictional products to be advertised (e.g., clothes, electronics, beauty products) and assign decimal values to each sponsored post (e.g., R$10.50, R$15.75).
-
Students must calculate the total earnings after one month of posting a certain number of sponsored posts. Example: 8 posts at R$10.50 each.
-
Groups should create a fictional post, including an image and caption, and explain how they calculated their earnings.
-
Groups present their calculations and posts to the class.
Activity 2 - Virtual Market: Online Buying and Selling
> Duration: 60 to 70 minutes
- Objective: Develop calculation skills with decimal numbers in the context of commercial transactions, integrating digital and collaborative skills.
- Description: Students will simulate the creation of a virtual market using a platform like Google Sites or a fictional Marketplace platform. They will list products with prices in tenths and hundredths, perform fictional transactions, and record calculations of total amounts after sales.
