'Be, Do, Have' Practice in Past Simple

I needed a practice sheet for my EFL 4th graders learning about past simple. I couldn't find one that covers all three of those verbs so I made one. It is a simple, clear worksheet, good to print if you happen to not have a colour printer (but to make it more flashy it could be printed on coloured paper) The clipart is from: http://www.clker.com/ The worksheet could be used to introduce the topic or for independent practice.
