Setting the Context

Hello, my dear children! Have you ever stopped to think about how our day is divided into many parts, from the moment we wake up to the time we go to bed? Yes, we are talking about time! Time is a very valuable resource, and knowing how to manage it efficiently is an incredible skill.

But how can we manage our time? To do this, we need to understand what we call time intervals. A time interval is the duration between two distinct moments, and we can measure this duration in hours, minutes, and even seconds. Why is this important? Because by understanding time intervals, we can organize our daily tasks, estimate how long it will take to carry out an activity, and even calculate the duration of events.

Introduction

Time intervals are formed by three main units: hours, minutes, and seconds. To understand this better, let's go on an imaginary journey, shall we? Let's imagine that we are in an amusement park and we want to know how much time is left until our snack, which will be served at 3 pm.

Do you know what a clock is? Of course you do, don't you? A clock is a tool that we use to measure time, and it is divided into 12 hours, each hour has 60 minutes, and each minute has 60 seconds. So, if it is 10 am now, how many minutes are left until our snack? And if it is 30 minutes, how many seconds are left?

These are some of the questions that we will learn to answer with the help of time intervals. And don't worry, because we will learn all this in a very fun way, through an amazing project! Come on, my dear children, let's embark on this time adventure! I am very excited to get started!

Practical Activity: "Time Travel"

Project Objective

The objective of this activity is to create a "Giant Clock" where students will explore the concepts of time intervals, such as hours, minutes, and seconds, and also develop social and emotional skills such as teamwork, time management, problem solving, and communication.

Project Description

The students, divided into groups of 3 to 5 members, will create a giant cardboard clock, where each group will be responsible for a time interval. They will have to represent on the giant clock the movement of the hands and the corresponding number of hours, minutes, and seconds, based on the time interval assigned to them.

Materials Needed

• Sheets of large cardboard
• Ruler
• Colored pens
• Blunt scissors
• Glue
• Adhesive tape
• Paper for notes

Step by step

1. Group formation: Divide the students into groups of 3 to 5 members.

2. Assigning time intervals: Each group should receive a card with a specific time interval, for example: 1 hour, 30 minutes, 15 minutes, 10 minutes, 5 minutes, 1 minute, and 30 seconds.

3. Giant Clock Planning: Each group must plan and draw on paper how the giant clock will be constructed. They should remember to include the numbers, the hands, and the correct division for each time interval.

4. Construction of the Giant Clock: With the materials in hand, the students will build the giant cardboard clock, following the planning they did earlier.

5. Giant Clock Decoration: The students should use the colored pens to decorate the giant clock. They can use their creativity and make the clock very beautiful!

6. Giant Clock Presentation: Each group must present their giant clock to the class, explaining the time interval they represented and how they did it.

7. Demonstration Activity: The teacher will ask the groups questions such as: "If it is 10:30 am now, what time will it be in 15 minutes?", "How many minutes are in an hour? And how many seconds are in a minute?", among other questions that explore the concepts of time interval.

8. Final Reflection: The students should write on a piece of paper what they learned from the activity, how it was to work in a team, if they faced any challenges during the construction of the giant clock, and how they managed to overcome those challenges.

Remember, the most important thing is to have fun learning! Come on, my dear children, let's get to work!
