A variety of tools are used to continue exploration into geometric figures and their transformations besides units of measure. Data analysis becomes important with collection and representation as well as relating experimental theoretical probability while making predictions. The real world becomes described in terms of patterns, functions, networks, and numerical relationships while using real life situations to illustrate the value of rational and irrational numbers. Seventh Grade - Seventh grade builds from 6th grade with still a great deal of emphasis on data. Number sense has settled around basic number relationships and operations of fractions, proportions, and percents continually strengthening that backbone of mathematics.
Geometry begins utilizing polygons and symmetry while calculating perimeter, area, and volume.
Data analysis concentrates on appropriateness of representation while continuing to make predictions of probable outcomes for larger populations. Again, patterns are related to real world situations in all areas besides numerical relationships. Rational and irrational numbers are explored by plotting and interpreting results and relating to real world problems. Eighth Grade - Eighth grade continues to concentrate in the same areas as fifth, sixth, and seventh. Number sense is the foundation on which all other strands rely.
