Standard Form
This excel file deals with the four operations on positive and negative numbers giving practice at a variety of calculations. The first four interactive sheet give sets of numbers to change into and from standard form. The powers of 10 may be positive or negative. The next interactive sheets deal with finding the sum, product, difference or quotient of numbers expressed in standard form without using a calculator. Initially pairs of numbers are combined with answers available at each step to aid understanding. Then sets of questions on each type of calculation are provided for further practice. There are a further seven sheets of questions which may be suitable for duplication for classroom use.
