This type of poster can be created with students during morning meeting on - how can we resolve conflict (after discussing what is conflict?) It can be posted in a reflection/ cool down zone with paper. I'd consider putting- "Talk to an adult for a big problem." or "Talk to an adult after trying two."
Disagreements happen and it is important for kids to be able to respond appropriately when they happen. Help kids master the skill of disagreeing with our FREE lesson plan. Includes printable classroom poster. I boystowntraining.org
