Multiplying by 10, 100 and 1000 - PowerPoint

This set of teaching resources is designed to help Year 5 students understand the concept of multiplying whole numbers by 10, 100, and 1000. The materials explain that when a number is multiplied by 10, its digits move one place to the left, and a zero is added as a placeholder in the empty place value column. For multiplication by 100, the digits shift two places to the left with zeros filling the new place value columns, and for multiplication by 1000, the digits move three places to the left with zeros added accordingly. The resources provide clear examples to illustrate these points, such as showing that multiplying 4, 7, and 30 by 10 results in 47 becoming 470, and so on for multiplications by 100 and 1000.

Further activities include comparing multiplications to determine which results in a greater value using signs like >, <, or =. For example, students are asked to compare 43 multiplied by 100 to 43 multiplied by 10. Additionally, there are exercises where students must fill in the missing numbers to complete calculations, such as finding what 4500 equals when multiplied by 100. The resources also offer real-life contextual problems, such as calculating how much more money one person has compared to another when their amounts are multiplied by 10. These teaching aids are designed to build fluency, reasoning, and problem-solving skills in multiplication and understanding of place value.
