Introducing division can be a tricky task. I've found that the best way to start the basic division unit is always with some hands-on equal groups activities and worksheets. I use this pack to introduce basic division to my 3rd graders, and it always helps to lay the foundation for the rest of the unit. This pack includes:
*Equal groups worksheet #1, where students are asked to divide a set of objects into equal groups, then write the division problem it represents. This helps the students to understand the meaning of "division" rather than simply providing them with an algorithm. This worksheet provides scaffolding.
*Equal groups activity sheet, which can be used as a math center or a whole class activity. For this, I assemble bags of common classroom items (crayons, linker cubes, etc.) and have the students physically sort the items into groups. This a great way to solidify their understanding from worksheet #1. This worksheet also provides slight scaffolding.
*Equal groups worksheet #2, which is similar to the first worksheet and activity sheet, but it does not provide the same scaffolding. This worksheet is more advanced and similar to the equal groups quiz at the end of the pack. This will help the students prepare for the quiz so that they know what to expect on the day of the quiz.
*Equal groups quiz. This quiz will assess whether the students mastered the concept of equal groups and are ready to move onto fact families and memorizing basic division facts.
Hope this is as helpful in your classroom as it is in mine. If you have any questions, feel free to send me a message!
