• ### Activity 1 / Adding Numbers: Landforms Worksheet

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.

• ### Activity 2 / Adding Numbers: Classifying Animals Worksheet

Animals can be classified into different groups, to make understanding them so much easier. In Biology, your children will be taught that animals can be grouped into Kingdom, Phylum, Class, Order, and Family. In this worksheet, your kids will be helping to find the different ways to classify animals. Help them solve each of the 5 different equations, and the circle the correct answer to find out.

• ### Activity 3 / Adding Numbers: Conservation Worksheet

The Earth is the planet we live on. The Earth holds all life forms, and provides us with the important things we need to survive such as food, air and water. However, humans don’t always repay the planet with kindness. Pollution, water wastage and global warming are just some of the ways we harm the planet. Teach your kids that there are some ways we can help Mother Earth to heal and thrive. Ask them if they can give you some examples on their own, and then solve the subtraction problems to find ways to help keep the Earth healthy. Check the correct answers.

So engaging
We love how we can focus on math with this app. It is engaging and we love how we are able to adjust and tailor the levels according to our son’s knowledge and skill levels!
Momma Anna
Daughter's favorite
Still a top favorite for our 7 year old. She loves earning her stars as she learns to trace letters and numbers. Coloring and the sounds are engaging and are on target for her age group and being Pre K.
