The concept of number and place value is fundamental in 11-plus mathematics. This topic encompasses reading, writing, and ordering numbers up to millions, as well as understanding the place value of each digit in a number.
Students should be able to read and write numbers accurately, including large numbers up to millions. For example, the number 3,456,789 can be read as 'three million four hundred fifty-six thousand seven hundred eighty-nine'.
Each digit in a number has a specific place value depending on its position. For instance, in the number 5,432:
Understanding place value helps students to perform operations and solve problems effectively.
Students learn to compare and order numbers, which is essential for understanding their relative sizes. For example, when ordering the numbers 23, 45, and 12, students should recognize that:
Rounding is another key skill. Students should be able to round numbers to the nearest 10, 100, or 1,000. For instance:
Understanding negative numbers is crucial, especially when comparing and ordering them. For example, when comparing -3 and -1, students should recognize that -3 is less than -1. Using a number line can help visualize this concept.
Number lines are a valuable tool for students to understand the position of numbers, including both positive and negative values. They can help in visualizing the order of numbers and in performing operations.
Mastering number and place value is essential for success in the 11-plus mathematics exam. It lays the groundwork for more complex mathematical concepts and problem-solving skills.
