This is a blog created to the Etwinning Project Fun and Math. A project directed to mathematics, focused on funny and stimulating activities for children, enabling them to gain some interest and pleasure for this subject, but also explore their logical-mathematical thinking abilities and skills. With this project we intend to share challenges, problems, online games and tasks that allow children to improve their performance in Math.

Count
A bartender paid 75 euros for 5kg of sausages. How much he
would pay for 3 kg of the same kind of sausages?
He would pay 45 euros
ReplyDeleteSão 45 porque se 15x5=75 mas o 15 representa quantos custam os quilos.
ReplyDeleteSe 15+15+15=3x15=45.
E se fossem 3 quilos pagaria 45 euros.
Excellent:-)
ReplyDelete15+15+15=45
