Hang on tight! Go on an off-road adventure with 4x4 vehicles that are built to handle the roughest terrain. Rocks, sand, and snow are no problem for these four-wheel-drive trucks. Hardworking engines and body-on-frame construction also give them the power to tow and do wilderness rescues. Engage struggling and reluctant readers with a topic kids love--transportation--and give them reading practice with content they can succeed with. Carefully leveled text paired with accessible infographics and in-your-face photos make this a perfect offering for reluctant readers. Sidebars and fun facts keep kids engaged. A table of contents, glossary with pronunciations, further resources, and an index all enhance comprehension.
