Max Maths, Year 4, Learn together, Comparing and ordering numbers up to 10000 (6)

In a Year 4 mathematics lesson from Max Maths, students are learning to compare and order numbers up to 10,000 with a focus on understanding how to find a specific quantity more or less than a given four-digit number using a number line. For example, to find one more than 5,328, students would look at the number line and identify the next number, which is 5,329. Conversely, to find one less, they would look for the previous number, which is 5,327. This simple yet effective exercise helps students to visualise and comprehend the concept of incrementing or decrementing numbers by one.

The lesson further explores changes in numbers by tens, hundreds, and even thousands. Students are asked to find ten more than 4,060, which would be 4,070, and ten less, which would be 4,050. They also work with hundreds, finding that one hundred more than 8,400 is 8,500, and one hundred less is 8,300. Lastly, they practice adding a thousand to a number, discovering that 1,000 more than 1,200 is 2,200. These exercises reinforce the understanding of place value and the base-ten system, which are fundamental concepts in mathematics for this age group.
