This lesson is an engaging resource where the children are classifying rocks based on their properties. When we completed this lesson, we had already done a lesson on the properties of different rocks so had findings to work with already. However, you could incorporate the properties into this lesson too. The lesson comes with the complete lesson PowerPoint and resources. Brief structure of lesson: Retrieval practice Name that rock Whole class quiz questions for property definitions Guided practice for classifying rocks Independent sorting and classifying rocks Challenge questions Extend to think about sorting into igneous, sedimentary and metamorphic
