Understanding Perimeter and Practice

Miss Alia teaches grade 5 students about perimeter through a song and interactive activities. The lesson includes calculating perimeter for simple and complex shapes, with a focus on understanding the concept and practicing independently. The session concludes with a motivational reminder to keep practicing mathematics.
