Whole Number 2 x 1 - Column Breakout (Level 3)

This math topic focuses on practicing the method of column breakout for multiplying 2-digit whole numbers by 1-digit whole numbers. Students are expected to decompose the 2-digit number into tens and ones, and then multiply each component separately by the single-digit multiplier to solve the problems. Each question requires identifying the correct decomposition and calculation to match a given expression. The problems range from multiplying numbers like 18 by 6 up to multiplying 26 by 6, enhancing skills in mental math and understanding the distributive property of multiplication.
