In 1983, Howard Gardner proposed the Theory of Multiple Intelligences. He believed that we all have a wide range of abilities, some people are just stronger in specific areas. I think Project Based Learning can help us reach every child, no matter what their strengths or weaknesses may be.

When you are designing your lessons (especially PBL units!), take into consideration this product grid. Think about each of your students and how you might adapt your expectations and assessments to meet individual learning needs.
