Blades is a state of the art science book based on the grasslands biome. Developed in collaboration with the Department of Biology at Doane University and a team of educators, Blades includes both interactive enhancements and universal design accessibility features.
Blades is part of our Crack the Books series of interactive non-fiction books. Crack the Books are the first digital books that can be ADJUSTED FOR READING LEVEL without sacrificing content. Our digital books allow for reading level adjustment from 1st grade to 8th grade, making it possible for all kids to access the same content regardless of their reading ability.
Designed with the goal of improving reading comprehension, fostering a love of learning, and building reading confidence, Blades gives parents a powerful new teaching tool to help all kids, from children with special needs to those who are academically gifted.
Blades covers a variety of topics, including the structure of grass, plant and animal wildlife, adaptations, benefits of grasslands, and grassland threats. Kids will learn about all major grassland ecosystems including tropical savannas, steppes, prairies, pampas, and velds.
Blades feature hundreds of supportive audio and visual elements including beautiful high definition photographs, integrated video footage, fun facts, custom animations, custom images, and interactive charts, tables and globes. There are comprehension supports built into the text, with pop up definitions for associated new vocabulary. Kids may further interact with the content by creating bookmarks, highlights and study notes.
For kids with special needs, there are additional settings for common accommodations including text to speech, answer dictation, image reinforcement and text zooming.
