Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Math Influencers 🚀

> Duration: 60 - 70 minutes

- Objective: Apply operations with real numbers in a digital and accessible format, developing communication and creativity skills.

- Description: In this activity, students will transform into digital math influencers. They must create a short video for a video platform (such as TikTok or YouTube) explaining operations with real numbers and fractional exponents. The goal is to teach the content in a creative and accessible way to their followers.

- Instructions:

  • Divide the class into groups of up to 5 students.

  • Each group must choose a specific aspect of operations with real numbers and fractional exponents to explain (e.g., how to calculate square roots using fractional exponents).

  • Students should use their cell phones to film the video and can edit using available apps like InShot or CapCut.

  • Encourage students to be creative, using stories, analogies, and even humor to explain mathematical concepts.

  • After creating the video, each group should post it on the chosen platform and share the link with the class.

  • Finally, promote a feedback session where groups watch each other's videos and discuss what they learned.

Activity 2 - Math Hacker Challenge 🕵️‍♂️

> Duration: 60 - 70 minutes

- Objective: Develop the capacity to solve mathematical problems collaboratively and engagingly, using digital resources to learn in a playful way.

- Description: Students will be challenged to solve a series of mathematical problems related to operations with real numbers in a simulated 'hacking' environment. Using an online gamification platform, students will need to solve each problem to advance to the next level.

- Instructions:

  • Divide the class into groups of up to 5 students.

  • Introduce the online platform that will be used for the challenge (e.g., Kahoot, Quizizz).

  • Each group must access the platform and start the challenge, where they will find mathematical problems about operations with real numbers and fractional exponents.

  • Problems must be solved as a team, and each correct answer will allow the group to advance to the next level.

  • Students can use the internet to search for additional information and verify their answers.

  • At the end, promote a discussion about the strategies used and the learnings acquired during the challenge.

Activity 3 - Space Mission: Calculating in the Cosmos 🌌

> Duration: 60 - 70 minutes

- Objective: Apply operations with real numbers in practical and scientific problems, developing problem-solving skills in teams.

- Description: Students will simulate a space mission where they need to use operations with real numbers to solve problems that will ensure the success of the journey. Using an online simulator, they must calculate trajectories, fuel consumption, and other vital parameters.

- Instructions:

  • Divide the class into groups of up to 5 students.

  • Each group must access an online simulator that allows performing mathematical operations in the context of a space mission (e.g., NASA's physics simulator).

  • Students will need to solve practical problems, such as calculating the amount of fuel required for a trip, using operations with real numbers and fractional exponents.

  • Groups must record their answers and justifications in a shared document (e.g., Google Docs).

  • After completing the mission, hold a debate session where groups share their experiences and discuss the solutions found.

  • Encourage students to reflect on the practical application of mathematical operations in real and scientific contexts.

Feedback
