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.
This is basic mathematics and number operations. Geometry, as in figural analogies and units of measure, is a branch in mathematics that can apply number sense to real world situations. Data organization, representation, and interpretation is directly related to real world problems and concentrates on those factors in eighth grade. Probability has greater emphasis than previous grades along with the more abstract ways of solving problems with number theory, diagram, and networks. Ninth Grade - Ninth grade covers topics equivalent to previous grades but expands into more encompassing areas.
