Noticing similarities and differences in shapes and designs is an important part of being mathematical. It is valuable for students to see that shapes and designs have many different characteristics and can be sorted in a variety of ways. This task is great for language development, being descriptive, paying attention to detail and being specific. These are all mathematical skills that are valuable to develop. This task also allows for them to be creative and create their own collections with a variety of characteristics. This activity is a series of sorting activities: sorting emoji, making their own collection for sorting, and sorting puzzles. You can split it into a series of 2 or 3 days of lessons depending on the amount of time you have for math in your class or chose one of the activities to do with your class.
