Max Maths, Year 3, Learn together, Addition up to 4 digits without regrouping (2)

In a Year 3 mathematics lesson from Max Maths, students learn to perform addition with up to four-digit numbers without the need for regrouping. The lesson introduces a practical approach to addition by breaking down numbers into their respective place values. For instance, Han tackles the problem of adding 128 and 451. He begins by creating the two numbers, carefully separating them into hundreds, tens, and ones. Han then combines these place values: the hundreds with hundreds, the tens with tens, and the ones with ones. Through this method, Han correctly concludes that the sum of 128 and 451 is 579.

Similarly, Jade is presented with the task of adding 1,502 and 267. She approaches the problem by constructing each number, again dividing them into their place values: thousands, hundreds, tens, and ones. Jade then combines these groups accordingly, ensuring that each place value is added to its like. By putting the place values together, Jade discovers that the sum of 1,502 and 267 amounts to 1,769. This methodical approach to addition helps young learners understand the concept of place value and how it aids in simplifying the process of adding larger numbers without the complication of regrouping.
