Howard Gardner proposed there are eight types of intelligence: linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic. He believed instruction should engage all intelligences through varied activities like role-playing, arts, and computer games. Teachers should assess students in different ways and use diverse tools in the classroom to accommodate the multiple intelligences of each child. When teaching, considering each student's strengths will help them learn in the optimal way.
