Learning outcomes After studying this course, you should be able to: write whole numbers and decimals in place-value columns and compare their sizes multiply and divide whole numbers and decimals by 10, 100, 1000 and so on indicate given fractions on a diagram and find equivalent fractions for a given fraction mark numbers on a number line choose appropriate units for a given purpose.

However, locating points whose coordinates are not whole numbers requires more precision when reading along the axes. For example, here the coordinates of the point A are (2.2, 1.8). 3.2 Negative coordinates Up to now only those points with positive or zero coordinates have been considered. But the system can be made to cope with points involving negative coordinates, such as (−2, 3) or (−2, −3). Just as a number line can be extended to deal with negative numbers, the x-axis and y-axis can be extended to deal with negative coordinates. 3.1.1 Try some yourself Write down the coordinates of A and B. 3.1 Positive coordinates For many towns and cities, an individual book of street maps called an A to Z has been produced. You can look up the name of a street in the index, and it will give you the page number of the map that contains the street, plus the grid reference square for the street. There are different conventions for these grid references. You may have met several of these. 2.3.1 Try some yourself This table categorises Tom's activities for the day.
