Mastering Multi-Digit Addition with Manipulatives

Grade 6 Special Education Resource Class Using Base-Ten Blocks and Calculators Building Number Sense and Fluency

Place Value Review

Ones place: single units (1, 2, 3...) Tens place: groups of ten (10, 20, 30...) Hundreds place: groups of one hundred (100, 200, 300...) Thousands place: groups of one thousand (1000, 2000, 3000...)

Hands-On Addition with Base-Ten Blocks

Work in pairs to solve: 247 + 156 Use base-ten blocks to represent each number Combine blocks and regroup when necessary Record your steps on whiteboards

Step-by-Step Addition Process

Using Calculators to Check Our Work

Calculators help us verify our answers Always solve the problem first, then check Read calculator displays carefully Compare your answer with the calculator result

Think and Discuss

When should we use mental math versus a calculator? How do manipulatives help us understand addition? What strategies help you check if an answer is reasonable?

Independent Practice

Solve these problems on your whiteboard: 358 + 274 = ? 146 + 287 = ? Use any method, then check with calculator

Key Takeaway

Understanding place value is the foundation of all multi-digit operations. When we know how numbers work, we can solve problems with confidence!
