Max Maths, Year 6, Learn together, Multiplying by a 1-digit number (1)

In the Max Maths Year 6 curriculum, students learn the process of multiplying a 3-digit number by a 1-digit number through a step-by-step methodology. The example provided illustrates how to multiply 243 by 4. The technique involves breaking down the multiplication by each place value—ones, tens, and hundreds—and then adding the results together to find the final answer. This method ensures a clear understanding of how multiplication affects each digit within the larger number.

Starting with the ones place, students multiply 4 by 3 to get 12. They then move to the tens place, multiplying 4 by 40 (the value of 4 in the tens place), which equals 160. Finally, they multiply the hundreds place: 4 by 200, resulting in 800. These individual products are then aligned according to their place values and added together. The sum of 12 (ones), 160 (tens), and 800 (hundreds) gives the final answer of 972. The process highlights the importance of moving down one line with each multiplication to maintain the correct place value alignment, ensuring accurate calculation and comprehension of the multiplication process.
