Hands-On Equations® Level 2 Continue the Fun Way to Learn Algebra! You've mastered the fundamentals. Now it's time for the next exciting step in your algebra journey! Hands-On Equations® Level 2 introduces an innovative new game piece—the white pawn, which represents the opposite of x. Using the white pawn together with the familiar blue pawn and numbered cubes, students learn elegant new strategies for solving increasingly sophisticated equations. Watch students confidently solve equations such as: 3x = –x + 4 and x – 3(–x) + 2 = 8 – 2x while enjoying the same highly visual, intuitive approach that has helped more than one million students better understand algebra. Discover More Advanced Algebra Naturally As students solve increasingly challenging equations, they intuitively apply important mathematical ideas, including: • Additive inverses • The additive property of zero • The addition property of equality As they solve these Level 2 equations, students discover how to add positive and negative numbers—without formal instruction. Rather than memorizing procedures, students develop a genuine understanding of why algebra works. Who Should Use Level 2? Hands-On Equations Level 2 is the natural continuation for students who have completed Level 1, including: • Gifted students in Grades 2 and above • Elementary students in Grades 4 and above • Middle school students • High school students who would benefit from a clearer, more visual approach to algebra • Adults who wish they had learned algebra this way the first time Experience Success. Build Confidence. As students experience continued success solving increasingly challenging equations, they develop greater confidence, deeper understanding, and an appreciation for the beauty and simplicity of algebra. If you enjoyed Hands-On Equations Level 1, you'll love discovering what you can accomplish in Level 2. For more information about Hands-On Equations, visit www.borenson.com.
