Geogebra2

Com o uso da  Geogebra calculadora 3D, pude desenvolver a construção do prayground onde as crianças poderão  se divertir  e interagir com a estrutura . 
O ambiente foi criado pensando no bem estar da criança. 
Partes da construção:
Foi utilizado 4 cubos grandes para fazer a torre . 
Foi utilizado 5 cubos menores para fazer o  túnio onde as crianças terão facilidades para passar por dentro.
Foi utilizado a ferramenta de retas e poligonos onde encontrei o  que precisava para fazer o escorregador para que as crianças possam se divertir escorregando.   Utilizei o segmento, que orienta  selecionar dois pontos para construção. 
Foi utilizado 2 cubos grandes para construir uma pilar onde se encontra escadas  que posibilita  que as crianças podessem subir para terem acesso ao túnio, escorregador e o balanço que está localizado na parte de baixa do túnio, para ter acesso ao balanço as crianças contara com ajudas de adultos.
