10 and 100 More or Less - PowerPoint

In this engaging mathematics resource for Year 3 students, the focus is on understanding and practising the concepts of finding 10 and 100 more or less than a given number. The resource includes a series of interactive PowerPoint slides and worksheets that prompt students to calculate and identify numbers that are either increased or decreased by 10 or 100. The activities are designed to reinforce students' number and place value skills, providing both visual aids and numerical problems to solve. For example, students may be presented with a number like 627 and asked to determine what 100 more would be, or given the number 485 to find what 10 less is.

The worksheets contain a variety of tasks such as filling in the blanks for numbers 10 or 100 more or less than those provided, true or false statements that require students to validate their understanding of place value, and problem-solving questions where students must use logical reasoning to find missing numbers. Some exercises also challenge students to identify the odd one out in a series of numbers, further testing their comprehension of the concept. The resource is designed to build confidence in number manipulation and to help students develop a firm grasp of place value, which is fundamental to their mathematical development.
