Contextualization

Hello, kids! Today we are going on an exciting journey through time. Yes, did you know that time is divided into parts called intervals? That's right! Time intervals are ways of measuring the passage of time in small portions, just like we use a ruler to measure lengths. They are very useful for our daily lives, as they help us organize our tasks, plan activities, and even tell stories.

Have you noticed how we use time in many things we do daily? When we wake up, for example, we look at the clock to see if we still have time to get ready and have breakfast before leaving for school. At school, we have schedules for each class, for recess, for lunch, and so on. And at home, we have to organize our time to do chores, study, play, and rest. All of this is possible thanks to time intervals.

Importance of Time Intervals

But why is it important to understand and know how to use time intervals? Well, knowing about time intervals is essential for better organization. When we know time intervals well, we can better plan our activities, avoiding delays and wasting time. And this is very valuable because time is a limited resource that we cannot recover once it has passed. Therefore, knowing how to manage time well is a very useful skill for life.

Furthermore, understanding time intervals also helps us better understand the world around us. For example, when we read a story, often the time in which the story takes place is important to understand what is happening. And when we study history, time intervals are essential to understand the order of events and how they relate. So, learning about time intervals is much more than just a mathematical skill, it is a tool that helps us better understand the world and become better managers of our own time.

The Importance of Mathematics

Mathematics is the universal language that helps us understand and describe the world around us. It is present in everything we do, from calculating change at the bakery to planning a trip, and even in the way nature organizes itself. Through mathematics, we can solve problems, make more informed decisions, and better understand how things work.

In this project, we will explore mathematics in a very fun and practical way, using the concept of time intervals. We will learn how to measure and compare time intervals, how to add and subtract time intervals, and how to use all of this in real-life situations. So, get ready for many challenges, games, and amazing discoveries!

Practical Activity: 'Managing our time'

Project Objective

The objective of this project is to allow students to understand and practice the measurement, comparison, addition, and subtraction of time intervals in a realistic and fun context. They will also develop socio-emotional skills, such as teamwork, problem-solving, and time management.

Project Description

Students, divided into groups of 3 to 5, will create a weekly calendar of the activities they perform at school and at home, using time intervals. They will record the time spent on each activity and calculate the total time spent each day. Then, they will analyze the collected data and discuss ways to better manage time.

Necessary Materials

• Large sheets of paper or cardboards
• Ruler
• Pencils and erasers
• Colorful markers
• Clock or cell phone to measure time (under adult supervision)

Step by Step

1. Group Formation and Planning: Divide the class into groups of 3 to 5 students and explain the project's objective. Each group should discuss and plan the activities they will carry out during the week at school and at home.

2. Creating the Calendar: Using the large sheets of paper or cardboards, each group should create a weekly calendar, with the days of the week (from Monday to Sunday) and the hours of the day (from 6 am to 8 pm).

3. Recording Activities: Each group should record on the calendar the activities they perform each day and each hour. For example, at school: math class, recess, Portuguese class, lunch, science class, etc. At home: dinner, bath, bedtime, etc.

4. Time Measurement: During the week, students should measure the time spent on each activity using the clock or cell phone (under adult supervision). They should write down the time spent for each activity on the calendar.

5. Calculating Total Time: At the end of each day, students should add up the time spent on all activities and write down the total time spent that day.

6. Data Analysis: At the end of the week, each group should analyze the collected data. They should discuss and answer questions such as: Which activities take more time? Which activities take less time? How can we use time more efficiently?

7. Presentation of Results: Each group should present the results of their analysis to the class. They should explain how they used time intervals to organize activities on the calendar, how they measured the time spent on each activity, and how they analyzed the collected data.

Remember, kids, this is a group project and everyone should participate. Work together, help each other, and have fun learning about time intervals!
