Max Maths, Year 2, Learn together, Subtracting tens and hundreds (4)

In a Year 2 Max Maths lesson, students are learning to subtract tens and hundreds from a given number. The lesson provides a clear and practical approach to understanding subtraction by using counting beads as a visual aid. When subtracting hundreds from the number 834, the lesson illustrates that by removing 100 at a time, the number decreases in hundreds while the tens and ones remain unchanged. For example, taking away 1 hundred from 834 results in 734, which is shown as 834 minus 100 equals 734. This process is repeated with subtracting 2 hundreds to get 634, 3 hundreds to get 534, and 4 hundreds to get 434. Each step reinforces the concept that only the hundreds place is affected during this subtraction.

The lesson emphasizes that when we subtract hundreds from a number, the digits in the tens and ones columns do not change. This key point helps students understand the place value system and how each digit within a number has a specific value depending on its position. After the demonstration, students are directed to workbook pages 52 to 54 to practice the concept further. Through these exercises, they become more confident in subtracting tens and hundreds and gain a better grasp of basic subtraction principles within the framework of the place value system.
