Mathematics 4 - Textbook
Math Around the World uses the same learning approach and covers the same material as the Math 4 LightUnit course. The textbook works equally well in homeschool and school settings. Students need to do their work on other paper, except for quizzes and tests. Reference numbers on exercises indicate the page number where the concept was taught. The textbook is more colorful than the LightUnits and contains 160 lessons.
You do not need to purchase LightUnits if you purchase the textbook.
