Math at Home
Today I explored a Web site with photographs of endangered mammals. I solved addition problems about how much the animals weigh, and learned many facts about them. I found out that one of the largest endangered mammals is the African elephant. It can weigh as much as pounds!
You can find out more about this topic by asking your teacher or parents to show you other Web sites.
