Thomas is busy traveling all over Sodor. Everywhere he goes there are things to find and things to count. With simple visual prompts, young readers have to find objects in each picture. Then they are asked to add or subtract some of these hidden items and they flip the flap to check their answer. A fun first math book featuring the simplest skills where no number is larger than 10. Thomas lovers will have hours of enjoyment with this unique new format, and never realize that they are reinforcing their math abilities!
