Max Maths, Year 5, Learn together, Written methods (2)

In a Year 5 mathematics lesson on written methods for addition, students learn to add two decimal numbers together, specifically 527.98 and 231.54. The process is broken down into clear, manageable steps that focus on adding each place value separately and carrying over when necessary. The first step involves adding the hundredths place: 8 hundredths plus 4 hundredths equals 12 hundredths. This is then renamed as 1 tenth and 2 hundredths, with the 1 tenth being carried to the tenths column.

The next step tackles the tenths place, where 9 tenths are added to 5 tenths, along with the 1 tenth carried over from the previous step, resulting in 15 tenths. This sum is then renamed to 1 one and 5 tenths, and the 1 one is carried to the ones column. In step three, the ones are added together: 7 ones plus 1 one plus another 1 one from the carry-over makes 9 ones. Step four adds the tens, with 2 tens and 3 tens combining to make 5 tens. Finally, step five adds the hundreds place, where 5 hundreds and 2 hundreds total 7 hundreds. The completed sum shows that 527.98 added to 231.54 equals 759.52, demonstrating the methodical approach to written addition of decimals.
