Comparing quantities or amounts in terms of more, fewer, or the same as helps with understanding the relationship between numbers. Quantity is related to ‘how many’ rather than size, shape, or position. Numbers can be compared by determining which one is greater than, less than, or equal to another number. For example,

 

Sometimes it is useful to arrange numbers in ascending or descending order.

For example, 20, 30, 40, 50 is arranged in ascending order (least to greatest) 50, 40, 30, 20 is arranged in descending order (greatest to least)

Understanding place value can help with comparing and ordering numbers. In our decimal number system the value of a digit depends on its place, or position, in the number. Each place has a value of 10 times the place to its right. For example in the number 42• the digit 2 is in the ones place• the digit 4 is in the tens place

Mathematical Words/Symbols used in ordering number include

Fewer – less than (<)

More – greater than (>)

Same as – equal to (=)

Digits – are the numerals 0 to 9 that form numbers. For example, the digits 2 and 7 can form the two- digit numbers 27 and 72. Mathematical Statement – consists of numbers and symbols defining a relationship of equality or inequality. An example of equality is 3+ 5 = 2 + 6. An example of inequality is 3+ 5 < 2 + 5.Place value – the value of any digit depending on its location in a number e.g., for the number 84 the place value of the 8 is 80.
