Teaching Patterns is a big part of Kindergarten (at least for now, the Common Core might change that). Whenever I teach patterns I use manipulatives. This allows the students to really work the objects in front of them to create their patterns. This helps make a connection with the patterns that crayons and paper can't always do. After this then you can move onto paper and pencil patterns. But please be sure to use your math manipulatives when teaching, the hands-on activities really make a difference with your kids.
