In I Spy Triangles, emergent readers learn to spot and identify different triangle shapes in a fun seek-and-find format. Carefully crafted text uses high-frequency words, repetitive sentence patterns, and strong visual references to support emergent readers, ensuring reading success by making sure they aren't facing too many challenges at once. I Spy Triangles includes tools for teachers and caregivers as well as introductory nonfiction features such as labels, a table of contents, words to know, and an index. A Let's Review! feature poses an image and question for further comprehension. I Spy Triangles is part of Jump!'s I Spy Shapes series.
