Pointsymmetry, also known as central symmetry, occurs when a figure has a symmetry with respect to a point. This means that if the figure is rotated 180 degrees around the central point, it will look exactly the same as the original figure.
Number and Operations: Students' work in dividing fractions shows them that they can express the result of dividing two whole numbers as a fraction (viewed as parts of a whole). Students then extend their work in grade 5 with division of whole numbers to give mixed number and decimal solutions to division problems with whole numbers. They recognize that ratio tables not only derive from rows in the multiplication table but also connect with equivalent fractions. Students distinguish multiplicative comparisons from additive comparisons.
