Summer has come and your grandmother is having you over for the weekend. It is usually very boring at your grandmother's house but she has promised that this time it will be lots of fun. Since it is raining outside, your grandmother suggests that you go look around the house for some gems. She has hidden at least 30 gems somewhere in the house. You arenít sure if this is going to be any fun but your grandmother just smiles and says that if you can find all the gemstones you can keep them and show them to your friends when you go back to school.
