Os
Números Naturais 



Ao observarmos ao nosso redor, podemos
perceber que, a todo o momento, as pessoas estão contando alguma coisa.
Contamos o número de crianças de turma, a quantidade de materiais escolares, o
dinheiro ...



Mas será que essa
forma de contar sempre existiu?

<![endif]--><!--[if !vml]--><!--[endif]-->Antigamente
o ser humano não contava porque não era necessário. A Matemática se desenvolveu
com o passar do tempo como uma linguagem numérica que partiu da necessidade do
ser humano. Assim surgiu os algarismos que conhecemos hoje e utilizamos para
contar. 



Iniciando pelo zero e acrescentando uma
unidade, teremos a sucessão de números naturais.


Fonte: &nbsp;eradamatematica.blogspot.com




0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 13, 14...



Todo número natural tem um sucessor, ou
seja, um número que vem depois dele.



O sucessor de 3 é 4, pois 3 + 1= 4.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 



E todo número natural, exceto o zero,
tem um antecessor, isto é, um número que vem antes.



O antecessor de 4 é 3, pois 4 – 1=
3&nbsp; 



É hora de praticar



Pense em algumas situações de seu dia a
dia que você utiliza a contagem e explique para que serve contar?



Explique para um colega como você
descreveria a sequência dos números naturais?



Qual é o maior número natural de quatro
dígitos que pode ser formado com os algarismos 1, 8, 0, 2, sem repeti-los? E o
menor?



Qual é o maior número natural de cinco
dígitos que pode ser formado com os algarismos 3, 7, 1, 9, 0, sem repeti-los? E
o menor?



Atividade Lúdica



Adivinhando o número....



Leia o desafio para um colega, para que
ele adivinhe o número.

Em que número pensei?



O número é o sucessor do antecessor de
7.

O número é antecessor do antecessor de
10.

O número é o antecessor do sucessor de
5.


O número é o sucessor do sucessor de
10.
