Cognitive skills development is the ability to acquire thinking skills. We believe children acquire these skills best when they are engaged in meaningful, hands-on experiences. When Ms. Sara has small rocks and big pinecones set out with a scale, she knows that children will compare, sort, organize and weigh these objects. She may ask questions like “Which group has more?” “Which group weighs more?” “How many are in each group?” “How can little rocks weigh more than big pine cones?” Children are learning math skills like organizing, comparing information, using weight as a measurement and counting. When Ms. Michelle shows children a coconut, hammer, protective eyewear and a tarp, she know that the children are going to experience cause and effect, coordinating eye-hand movements, have opportunities to learn new vocabulary and talk about fruit-bearing trees.
