The first and easiest use of the mat is to help students to use connectives in their writing. I actually score their writing when we focus on connectives. This however opens the risk of over use.
Another way to use it is for students to sit in pairs and make up sentences including one of the connectives and collecting counters for the words that they use. The trick is to make it make sense.
The file includes the same mat but in three difference sizes. A4 A5 A6.
