Math LightUnit 201 reviews concepts that should be adequately mastered in order to succeed in Level 200. It can be used as a diagnostic tool.
The remaining nine LightUnits teach new skills and concepts such as telling time, reading simple graphs, adding/subtracting multi-digit numbers with carrying/borrowing, working with money, basic fraction concepts, and measurement in both the U.S. and metric systems.
Daily review on the addition/subtraction facts from 1-20 ensures mastery. Multiplication is introduced in Math 206, and by the end of the course, students have memorized the tables for 0, 1, 2, 5, and 10. Each lesson contains a realistic story problem or two using a theme (which varies with each LightUnit) such as pets, grandparents, and springtime.
The Teacher's Guide provides ideas, useful appendices, alternate LightUnit tests, and answers to the LightUnits. Answer keys are optional if the Teacher's Guide is purchased.
