There is a contest at a school to design a new playground. The students use blocks to build their models. As they build, they''ll need to use three-dimensional shapes to complete their visions of the perfect playground. With vibrant photos, math charts and diagrams, grade-appropriate text, and informational text features to help navigate the text, students will learn about practical, real-world applications of math skills as they learn 3-D shapes and build their STEM skills.
