About this worksheet

The whole trick is lining up the decimal points so tenths add to tenths and hundredths to hundredths. Writing zeros at the end (3.4 as 3.40) keeps the columns even without changing the value.

Teaching tip

For in-line problems, have students rewrite each one stacked before they add. Most errors come from skipping that step.
