There's a new resource pack available on the Planet that will save you time making Container activities. It's called "Containers Made Easy 1 Resource Pack." The pack has templates and directions for creating interactive Container activities. It takes the long process of creating a container activity and makes it faster for teachers!
The Resource Pack contains two folders: Templates and Word Matching. The templates include: 2-square chart, 3-square chart, 4-square chart, t-chart, Venn Diagrams with 2 and 3 circles, and more. The description on the site says, "The example flipchart starts with a completed example page, followed by page with a video capture (Quicktime) of the example being created, and finally a page for you to practice on (with page notes to follow along!)." Go to the Planet, search for "Container" as a keyword in Resource Packs, and download it today! Enjoy!
