Salvar la cultura en una catástrofe

Practice addition at the playground! This fun title, that has been translated into Spanish, uses examples from all around the playground to help children practice their addition and understand early STEM themes. Add up two blue swings and three red swings to get five swings! Add slides, rings, jump ropes, basketballs, and more! These familiar images work in conjunction with engaging "You Try It!" problems to encourage young readers to practice and improve their addition skills.

If it were possible to shrink down and take a tour of a human body, would you want to go? Readers will get that chance when they explore the body of a guy named Marty, who will let them check out the body systems that keep his heart beating and his body moving every day. With the help of a tiny ship that goes through his ears and all the way through his digestive system, readers will learn exactly what they are made of with this great book.
