Math is one of the subjects that elementary school teachers spend the most time teaching. The World Almanac® for Kids Elementary now has a new topic area—Math: Addition—to help young learners practice their math skills and tackle addition concepts from different, fun angles. Each section includes four-color images and diagrams and is supplemented with Fun Facts articles on light, entertaining topics such as “Monkey Mathematicians”; editorially selected videos; and games and puzzles that reinforce lesson concepts.
Sections of the new Math: Addition topic area include:
- Understanding Addition, covering “What Is Addition?”, “Why Addition Is Important,” and “Addition Symbols and Terms”
- Adding within 20, including “Models for Adding within 20,” “Strategies for Adding within 20,” and “Addition with Three Addends”
