Since 1958, our award-winning products have helped students of all abilities achieve better academic results with highly effective lessons that sharpen the mind as they teach standards-based reading, writing, mathematics, science, and history. Our products are fun, easy to use, and guaranteed to produce better grades and higher test scores. We design critical thinking into our reading, writing, math, science, and history lessons so students carefully analyze what they are learning. Deeper analysis produces deeper understanding, which results in better grades and higher test scores. Over time, students who practice critical thinking learn to apply it throughout their education and lives.
