Number Sense (NS)
Children learn the meaning of numbers in the everyday experiences that adults provide in the home, classroom and in their experiences of God’s creation. Preschool children need opportunities to watch, play and interact with adults and other children to learn number vocabulary and to discover number relationships. Developing number sense means more than merely counting. It involves the ability to think and work with numbers easily, to understand their uses and to describe their relationships.
Computation ( C)
Learning to model, explain and use addition and subtraction concepts in problem solving situations begins with the opportunity for young children to count, sort, compare objects and describe their thinking and observations in everyday situations. In building the foundation for computation, children need opportunities to observe adults and peers applying mathematical concepts and using problem-solving techniques.
Algebra and functions (AF)
Young children build the foundation of finding patterns and their relationships by exploring environments that are rich in shapes, sizes, colors and textures. They learn to identify and describe patterns using mathematical language when there are opportunities to sort, classify and label things in their environment. Children need hands-on activities to explore and describe patterns and relationships involving numbers, shapes, data and graphs in problem-solving.
Young children need opportunities to explore the size, shape, position and movement of objects within their physical environment. Spatial reasoning begins as children become aware of their bodies and personal space. Children learn to recognize, draw and describe shapes by manipulating, playing with , tracing and making common shapes using real objects in a variety of activities.
Children need many opportunities to explore and discover measurement and apply the results to real life situations in order to construct concepts of measurement.
