You can print out all letters twice, or print all letters once and include the extra vowel and common letters provided.
To use in the classroom, you can pick random letter cards and stick them onto the board. The children can use the templates provided (or a copy/ blank sheet!) to write down as many words as they can make using the letters on the board. You can give prizes/ stars to the children that get the most words, or get the word with the most letters!
