Max Maths, Year 4, Learn together, Multiplying 2-digit numbers without regrouping (3)

In a Year 4 mathematics lesson, students are learning to multiply two-digit numbers by single-digit numbers without the need for regrouping. The lesson demonstrates the column method, a systematic approach to multiplication that aligns numbers by place value. To illustrate, the task is to find the product of 23 and 3. Students are instructed to write the two-digit number (23) at the top and the single-digit multiplier (3) beneath it, ensuring each digit is placed in the correct column – ones under ones and tens under tens.

The first step in the column method is to multiply the ones. Students multiply 3 ones by 3, resulting in 9 ones, which is then written directly below in the ones column. Next, they move to the tens column, multiplying 2 tens by 3, which equals 6 tens. This product is placed in the tens column. By following these steps, the students find that the number 23, when multiplied by 3, gives a product of 69. This methodical process helps students understand multiplication without the complexity of regrouping, building a strong foundation for more advanced arithmetic operations.
