Geometry is a language of mathematics that is used to communicate the properties of and relationships between objects. Experiences related to the recognition, visualization, representation, and transformation of geometric shapes and their properties from real-life experiences long before they computed. Mathematicians continue this process today as powerful models of our world are developed. Students spatial capabilities often exceed their numerical skills and tapping these strengths can improve number understandings and skills as well as pique as interest in mathematics. Geometry is connected to every strand in the mathematics curriculum and therefore should not be restricted to a formal deductive study.
Measurement is a dimension, quantity, or capacity determined by comparison to a standard unit.
The study of measurement provides useful and practical applications of mathematics and involves making connections within mathematics and across the curriculum. Students develop their understanding of measurement and systems of measurement through experiences that enable them to use a variety of techniques, tools, and units of measurement to describe, analyze, and answer quantifiable questions and phenomena. Number sense is the ability to interpret and use numbers in counting and measurement situations and to sense the reasonableness of results. Numbers are an important part of daily lives. A person's ability to perform numerical calculations does not guarantee the acquisition of number sense.
