A digit is one of the symbols of a number system. In our number system we use the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

An integer is any positive or negative whole number or zero. E.g. -2, 0, 153 are all examples of integers.

Securing understanding of place value in integers

Maths

This unit on place value allows pupils to develop the skills needed to estimate and round values. By understanding the value of each digit, pupils can determine what other values are close to the original value. It continues the exploration of the infinite nature of sets of numbers.

This unit looked at the composition of numbers containing up to 7 digits and how to read these numbers
