This unit on number systems is in three parts.  The first part will be to develop in children a sense of numbers, the idea of quantity, counting and mathematical manipulation, collections of quantities and developing a unit of measure.  The second would be to develop the ideas of the negative numbers and build an understanding based on the manipulations of numbers.  The third part would be to introduce the number line as a continuum and to introduce ideas of fractions and rational numbers.While this is for classes 7and 8, we understand that students may come with very limited sense of the numbers.  So the activities are designed in such a way as to help such students also.
