Land is the Earth we live on. Some parts of the planet are covered in water, and the rest of the planet is covered in sprawling expanses of land. Man lives on this land, plants grow on land, and even animals make land their homes too. However, not all land is flat. There are mountains, which rise high to some of the highest points on the planet. There are valleys, which sink low, and there are hills also. Help your kids solve the simple equations and find the correct answers to move from the valley to the mountain top. Then, check the correct answer.
