Vocabulary - Place Value

The vocabulary list provided is an essential toolkit for understanding place value, a fundamental concept in mathematics, particularly for KS2 students. The list begins with the basics, such as 'units', 'ones', and 'tens', which are the building blocks of our number system. These terms are crucial for grasping how numbers are constructed and how each digit has a specific value depending on its position. For example, in the number 345, the '5' is in the units or ones place, the '4' is in the tens place, and the '3' is in the hundreds place. The terms 'digit' and 'number' are also introduced, with distinctions made between one-digit, two-digit, and three-digit numbers, expanding the child's understanding of number size and scope.

As the vocabulary list progresses, it delves into more complex terms such as 'teens' number, which refers to numbers from 13 to 19, and 'place value', which is the value of where the digit is in the number. The list also includes comparative terms like 'greater', 'less', 'largest', and 'smallest', which are essential for comparing and ordering numbers. Sequential terms such as 'first', 'second', 'third', and so on, teach students about ordering and positioning. The list also covers mathematical operations like 'addition' and 'subtraction', using phrases like 'one more', 'ten more', 'one less', and 'ten less'. Advanced concepts such as 'rounding' to the nearest ten, hundred, or thousand are also presented, along with the notion of 'decimals' and 'fractions', which are vital for understanding parts of whole numbers. Overall, this vocabulary serves as a foundation for mathematical literacy and numeracy skills.
