This presentation with pictures of food to discuss about food are good/ not good for health.

I used this powerpoint to discuss with my class about how to be safe when going out.

It is so important to set the rules for the kids in classroom in the beginning of the year. You can use this powerpoint to introduce for everyone at first, then dont forget to print these slides, laminate them and stick them to the class rule board - where the children could easily to see. Hope you can use this resources to help you in classroom management.
