Counting Forwards or Backwards in Powers of 10 - PowerPoint

A PowerPoint resource for Year 5 pupils focuses on understanding and practising counting in powers of ten. Powers of ten are explained as the number 10 multiplied by itself a certain number of times, such as 10, 100, 1000, and so on. The presentation guides students through the process of counting forwards in powers of 10, starting from any given number. For instance, if beginning at 53,197 and counting on in steps of 10,000, students would progress to 63,197, 73,197, and continue in that pattern. The slides are designed to help students grasp the concept of adding multiples of 10, 100, 1,000, and larger powers of ten to any starting number.

Additionally, the resource also tackles counting backwards in powers of ten, which involves subtracting powers of 10 from a starting number. For example, starting at 93,197 and counting backwards in steps of 10,000 would lead to 83,197, 73,197, and so forth. This exercise helps students understand the concept of decreasing a number by powers of ten. Worksheets are included to provide practice in both counting forwards and backwards, with exercises that require filling in missing numbers in a sequence. These activities solidify the understanding of place value and the base-ten number system, which are fundamental concepts in mathematics education.
