Great warm up activity for little ones!
Act like the animal.
Ask a random child what their favorite animal is. Have the entire group of children move like that animal to the other side of the room. For example, my favorite animal is a giraffe. Lets all walk on our tippy toes really tall. Once to the other side, ask another child what their favourite animal is. Repeat until every child has a turn. This game works best if the leader says their favorite animal first.
Look out for others.
