A
contagem e o nosso sistema de numeração 



Os números naturais estão presentes em
nosso dia a dia e são utilizados para as mais diversas finalidades. Usamos os
números para realizar contagens, ou seja, para responder a perguntas do tipo
“quantos?” (“40 alunos”, “já tenho 12 anos”, “tenho 10 reais a mais que você”,
etc.). Podemos também identificar um objeto de uma ordem, respondendo a
perguntas do tipo “qual?” (“o primeiro andar”, “o décimo na fila de espera”,
etc.).



Para se divertir! 



Leia a tirinha.

Jogo MAIOR LEVA. 



Para este jogo serão utilizados 40
cartões, como ilustrado ao lado, que apresentam a representação numérica e
pictórica dos números de 1 até 100. Os cartões são divididos por duas crianças.




Cada criança abre um cartão de seu
monte e os valores são comparados. Quem tiver o maior valor, fica com os dois
cartões. Em caso de empate, novos cartões são abertos e o aluno que tiver o
maior número nesta nova rodada ganha os quatro cartões. Ao final do jogo, ganha
quem tiver mais cartões.
