A great easy project for junior year levels. We used some fish templates but you could just as easily draw your own. We did some paper marbling and then, when they were dry, we drew 'wavy' lines. We cut along each line and then collaged them to create a layered effect.
We coloured our fish and then used sequins and googly eyes to decorate them. You could always add some glitter as well! Rather than glue our fish down, we added a velcro dot - this way the kids could reposition their fish or use them for storytelling.
