Place Value - Hundreds, Tens and Ones - PowerPoint

Understanding place value is fundamental in mathematics, and this concept is thoroughly explored in a Year 3 teaching resource focusing on hundreds, tens, and ones. The resource begins by clarifying that all numbers are composed of digits, with numbers from 0 to 9 being one-digit numbers. Students are taught that each one-digit number consists of a certain number of ones. They then learn that ten ones make a 'ten', and this notion is extended to two-digit numbers, which range from 10 to 99 and are made up of tens and ones. For example, the number 24 is broken down into 2 tens and 4 ones, with the first digit indicating the number of tens and the second the number of ones. This breakdown is further illustrated with numbers such as 51 and 79, helping students visualise the composition of two-digit numbers.

Building on this, the resource delves into three-digit numbers, which are composed of hundreds, tens, and ones, covering the range from 100 to 999. Students are shown how to deconstruct three-digit numbers into their constituent parts. For instance, the number 124 consists of 1 hundred, 2 tens, and 4 ones. This method is applied to other numbers like 342 and 517 to reinforce the concept. The resource includes worksheets where students can practice identifying the value of digits in various numbers, such as determining that the 3 in the number 637 represents thirty. They also learn to break down numbers written in words, like 'two hundred and sixty-eight', into their numerical form, 268. This comprehensive approach to place value equips students with the knowledge to understand the worth of each digit based on its position in a number.
