Max Maths, Year 5, Learn together, Written methods (1)

In a Year 5 mathematics lesson, students are introduced to written methods for addition with a focus on decimal numbers. The lesson presents a practical scenario: Han has a sum of money in his bank account ($468.47) and receives an additional amount from his grandfather ($364.53). The task is to calculate the total sum Han has now. The problem is approached step by step, breaking down the addition process into manageable parts that deal with hundredths, tenths, ones, tens, and hundreds separately.

The first step involves adding the hundredths, where students learn to carry over once the sum reaches 10 hundredths, converting it into 1 tenth. The next step is to add the tenths, again carrying over when the sum equals 10 tenths, which is equivalent to 1 one. The process continues with the addition of ones, where a carry over is also required. Steps four and five deal with adding tens and hundreds, respectively, each time carrying over to the next place value when necessary. The final result of the addition is a whole number, $833.00, which represents the total amount of money Han has after receiving his grandfather's gift.
