This is essential in an information society. Students use real tools to measure real objects. Measurement also includes the use of nonstandard tools of measurement. Students investigate the connection between mathematics and the world around them in both a concrete and an abstract geometric sense. The number strand permeates all the other strands.
Students learn how to use different kinds of numbers and basic operations.
The central concept of proportional relationships is the representation of one quantity as a proportion of another. Proportional relationships are the foundation of much of the mathematics that occurs in the real world. The students explore and understand ratio, rate, percent, slope, similarity, and probability. Multiple Representations Mathematical represenations are ways of presenting information and relationships that arise when problems are anlyzed. Students work with different represenations of number, as decimals, fractions, percents, or scienfitifc notation.
