This book is an electronic flip book, which means each page is set up like a movie frame. You need to scroll it at a steady pace to see the animation. Students go on a frame-by-frame journey to Mars, and gain knowledge about it. They also learn how to make calculations about its size, gravity and distance from the earth. The step-by-step solutions to the math questions are shown afterwards so students can check their work. Vocabulary words are highlighted in red with links to their definitions. The flip book format provides a fun visual and kinesthetic approach to learning!
