Contextualization

Hello, little mathematicians! We are about to embark on an adventure in the world of mathematics. Have you ever stopped to think why mathematics is so important in our lives? Well, mathematics is present in everything we do, from simple things like counting the toys we have to more complex things like solving logic problems. In this project, we will focus on a very important part of mathematics, which is natural numbers.

Natural numbers, as the name suggests, are the numbers we use to count things, such as: 1, 2, 3, 4... and so on. They are like the bricks with which we build mathematics. By learning about natural numbers, you will be able to solve many mathematical problems and, moreover, you will realize how mathematics is present in our daily lives.

Introduction

Now, let's talk a little about the specific theme of this project: "Comparison of Naturals Less than 20". It is very important to know how to compare natural numbers, as this helps us better understand the notion of "greater than" and "less than", which are fundamental concepts in mathematics.

Through the comparison of natural numbers, we can see that some numbers are greater than others. For example, 7 is greater than 5. But not all numbers are greater or less than others. Some numbers are equal. For example, 3 is equal to 3. Learning to compare numbers helps us understand these differences.

Now, you must be wondering how we are going to work on this theme in a fun and practical way, right? Well, that's what we are going to discover together throughout this project. Are you ready for the adventure? So, let's go!

Practical Activity: "Adventure in the Land of Numbers"

Project Objective

The objective of this activity is to allow you, little mathematicians, to explore the world of natural numbers less than 20 in a fun and practical way. You will work in groups to create a "Land of Numbers", where each number from 1 to 20 will be represented by a natural element or an everyday object.

Project Description

In this project, each group will create their "Land of Numbers", which will be a visual space where each number from 1 to 20 will be represented by something. For example, the number 1 can be represented by a tree, the number 2 can be represented by a bird, and so on. You can use creativity to choose the elements that will represent each number.

Then, you will compare the numbers and write down in a small notebook the comparisons you made. For example, you can say that the tree (which represents the number 1) is smaller than the house (which represents the number 5).

Necessary Materials

1. A3 paper sheets or cardboard to create the "Land of Numbers"
2. Colored pencils, markers, or crayons for drawing
3. Blunt scissors
4. Glue stick
5. Old magazines, newspapers, or prints for cutting and pasting (optional)
6. Small notebook and pencil or pen for writing the comparisons

Step by Step

1. Group Formation: Students will be divided into groups of 3 to 5 members.

2. Planning the "Land of Numbers": Each group should plan which natural elements or everyday objects will represent each number from 1 to 20. Make a draft on paper to think about it.

3. Creating the "Land of Numbers": Next, each group should create their "Land of Numbers" on A3 paper or cardboard. Draw or paste the elements you chose to represent each number. Remember to write the number next to each element.

4. Comparing the Numbers: After creating the "Land of Numbers", each group should compare the elements and write in the small notebook the comparisons they made. For example: "The butterfly (which represents the number 3) is smaller than the sun (which represents the number 10)".

5. Presentation of the Works: Finally, each group should present their "Land of Numbers" and the comparisons they made to the class. Get ready to explain the choices you made and how you made the comparisons.

Delivery Format

Students must submit the small notebook with the written comparisons and the drawing of the "Land of Numbers". The project will be evaluated according to the creativity in representing the numbers and the accuracy of the comparisons made.

This project will help you better understand natural numbers less than 20, as well as work on important skills such as teamwork, communication, and problem-solving. Have fun exploring the "Land of Numbers"!
