Lynette conducted a training session on abacus usage and arithmetic operations, focusing primarily on teaching subtraction methods and demonstrating how abacus-based learning differs from traditional mainstream math approaches. The discussion included practical demonstrations of various subtraction techniques, with emphasis on helping students understand place values and mathematical concepts more intuitively through verbalization and pattern recognition. Participants explored different teaching strategies and agreed on next steps for incorporating these methods into their ongoing math instruction with students.

1. Core Abacus Instruction
• How to read and use an abacus, including bead values (top beads = 5, bottom beads = 1)
• Basic counting and number representation on the abacus
• Available workbooks for 2-digit, 3-digit, and 4-digit number practice
2. Subtraction Methods and Techniques
• Abacus subtraction patterns and formulas (e.g., minus 9 = minus 10 plus 1)
• Two-step subtraction problems and when they occur
• Left-to-right vs. right-to-left approaches for subtraction
• The importance of verbalizing calculations to reinforce understanding
3. Abacus vs. Mainstream Math Comparison
• Key differences between abacus and traditional math teaching methods
• How abacus focuses on the "second number" (bottom number) rather than the top number
• Place value understanding through abacus visualization
• Trading concepts and how they differ between methods
4. Teaching Strategies and Best Practices
• Pattern recognition in mathematical operations
• Interactive math teaching formats and materials
• The importance of writing formulas alongside abacus work
• Using running totals instead of column-by-column calculations
• How abacus simplifies complex mathematical strategies
5. Practical Applications
• Real-world examples of abacus problem-solving
• Discussion of student progress and practice methods
• Integration with existing math curricula like Math with Confidence and Beast Academy
