Why use these well-loved manipulatives to teach students to understand fractions? Using manipulatives to demonstrate mathematical concepts can be an extraordinarily effective teaching technique to develop students' understanding. Experienced teachers recognize that for manipulatives to work effectively, activities must engage students and activate their prior knowledge and intuition. Using LEGO bricks in the mathematics classroom not only fulfills these requirements for a good lesson with manipulatives, they can also teach a wide variety of mathematical concepts at a relatively low cost.
