Children learn as they do. Hands-on learning is an excellent way for children to learn. It reinforces information taught or read. It allows children to experiment and to discover. Manipulatives should be used whenever their use will assist in learning.
Classroom management requires balance.
Children need rules in order to know how to appropriately behave. These rules should be consistenly reinforced. Children also need freedom to make choices and to communicate with their peers. Thus, the balance comes when children are given choices at appropriate times. Instruction dictates grouping.
