Ordering Numbers to 20 - PowerPoint

In a set of Maths teaching resources aimed at Year 2 students, the focus is on the concept of ordering numbers up to 20. The lesson introduces the idea of placing numbers in both ascending and descending order. Ascending order is explained as arranging numbers from the smallest to the largest, effectively 'going up'. To illustrate, the resource shows a sequence of numbers in ascending order, starting with the smallest number and increasing in value. The teaching method involves identifying the smallest number first and then progressively finding the next smallest until all numbers are ordered correctly. This foundational skill in number and place value is reinforced through interactive PowerPoint slides and hands-on practice.

Descending order, on the other hand, is the process of arranging numbers from the largest to the smallest, or 'going down'. The resources guide students through the process of finding the largest number first and then sequentially picking the next largest until all numbers are in descending order. Worksheets are provided to allow students to apply what they have learned by placing given sets of numbers into ascending and descending order. These exercises are designed to enhance students' understanding of numerical sequences and their ability to manipulate and order numbers within the 1-20 range, a key skill in early mathematics education.
