For more than 60 years, our award-winning products have helped students of all abilities achieve better grades and higher test scores 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 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 life. We do not teach through drill and memorization or teach to the tests—we empower the mind! Our goals are higher grades, top test scores, and problem solving skills to meet all of life’s challenges. We supply educational materials to Sylvan Learning Centers, Club Z In-Home Tutoring, the top U.S. public high schools, and gifted & talented programs throughout the world! We guarantee better grades and higher test scores—or your money back. Children love our products and you'll love what our products do for your child.
