Contextualization

Hello, little mathematicians! Let's embark on an exciting journey through the world of numbers together. In our project, we will explore the Natural Numbers Less than 100. But what are these numbers? Well, natural numbers are those we use to count things, like 1, 2, 3, 4, 5... and so on. The numbers less than 100 are all the natural numbers from 1 to 99.

Numbers are amazing! They help us understand the world in ways we can't even imagine. They are the language mathematicians use to describe how things work. But besides that, they are also very useful in our daily lives. Have you ever stopped to think about how many times we use numbers in our routine? From counting toys to knowing how many days are left until our birthday, numbers are always present.

Introduction

Now, let's learn a very important concept, which is comparing numbers. Comparing numbers is a skill we use every day, even without realizing it. When you say that one toy is bigger than another, you are comparing. When you say you have more candies than your friend, you are comparing. And guess what? We can also compare numbers!

We compare two numbers to see which one is greater, smaller, or if they are equal. Knowing how to compare numbers helps us better understand how numbers work and how they relate to each other. And that is very important because it helps us solve math problems and make decisions in our lives.

Now that you know what natural numbers less than 100 are and how to compare them, are you ready for a challenge? Our project will allow us to put all of this into practice in a very fun and interactive way. Let's do this!

Practical Activity

Activity Title: "The Treasure Hunt of Numbers"

Project Objective

The objective of this project is to allow students to explore, in a practical and fun way, the natural numbers less than 100, making comparisons between them and understanding the relationships of greater, smaller, and equal.

Detailed Project Description

In this activity, students, organized in groups of 3 to 5, will become true "number hunters"! Each group will receive a table with natural numbers less than 100, arranged randomly. The students' mission will be to organize these numbers in ascending and descending order, and then make comparisons between them, identifying which number is the greatest, the smallest, or if they are equal.

Required Materials

1. A3 paper sheets or cardboard
2. Pencils, erasers, rulers, and colored markers
3. Glue
4. Scissors
5. Table with natural numbers less than 100 (each table should contain 25 numbers, from 1 to 99, arranged randomly)

Detailed Step-by-Step for Activity Execution

1. Group Formation: Divide the class into groups of 3 to 5 students. Each group will receive a table with natural numbers less than 100.

2. Organization of Numbers: Each group should cut out the numbers from the table and glue them on their A3 paper or cardboard, in an order they consider random.

3. Sorting Numbers: After gluing all the numbers, the students should organize them in ascending order (from smallest to largest) and in descending order (from largest to smallest), writing the sequences below the numbers. For example, if the number 10 is below 5, the students should write "10, 5" below those numbers.

4. Number Comparison: Now comes the most fun part! The students, in each sequence they wrote, should compare the numbers, identifying which is the greatest, the smallest, or if they are equal. They should mark the greatest number with one color, the smallest with another color, and the equal ones with a third color.

5. Presentation of Results: Each group will present to the class their "Treasure Hunt of Numbers", explaining how they organized the numbers, how they made the comparisons, and which numbers they found in each category (greater, smaller, equal).

6. Classroom Discussion: After all presentations, the teacher will lead a discussion in the classroom, reinforcing the concepts of natural numbers less than 100 and number comparison. Students will be able to share their experiences, difficulties, and learnings during the activity.

Delivery Format

Each group must deliver the A3 paper or cardboard with the numbers glued and the sequences of numbers organized and compared. In addition, each student must write a short text (on a separate sheet) telling about their experience in the "Treasure Hunt of Numbers", what they learned, and how they felt while doing the activity.

Remember, the most important thing is to have fun, learn, and work as a team! Good luck, little mathematicians!
