Here is the target board. Just download, print and laminate. Then write on it with a whiteboard marker and change the numbers each week.
Here are the letters and heading for the Boggle board if you want to download them. I printed the heading on coloured paper and printed, laminated and cut the letters. I put velcro squares on the letters so I can change them easily.
As you can see, my Boggle board is shamefully boring. I'm sure it could be made a lot more pretty so I'll leave it to your own creative devices to make it more aesthetically pl
Here is a fantastic sheet for the children to use (especially if they have a "busy folder" for early finishers) that I found on Create Teach Share. You could write your own letters onto this sheet and photocopy if you have an emergency substitute folder.
Also, I've been nominated in the Best Teacher Blog category of the Edublog Awards 2011. If you read my blog and would like to vote for me, you can do so here. And if you REALLY like it, you can vote once a day! ;)
