Comparing Decimals, step by step
Decimals are compared from the left, place by place — exactly like whole numbers.
- LINE UP THE POINTSWrite one above the other with the decimal points in a column.
- EVEN THEM UPAdd zeros to the right so both have the same number of places. 0.7 becomes 0.70.
- COMPARE FROM THE LEFTWhole numbers first, then tenths, then hundredths.
- STOP AT THE FIRST DIFFERENCEThat digit decides it. Ignore the rest.
worked
- 0.7 vs 0.65 → 0.70 vs 0.65 → 7 tenths beats 6 tenths → 0.7 wins
- 3.40 vs 3.4 → identical. Trailing zeros change nothing.
More digits does not mean bigger. 0.9 is larger than 0.1234.

- Who is the Comparing Decimals poster for?
- Comparing Decimals is filed under 4th Grade (ages 9–10), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Comparing Decimals poster?
- Give both numbers the same number of decimal places, then compare as normal. A wall chart earns its place by being glanceable from where the work is happening, so Comparing Decimals belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Comparing Decimals?
