How to use these worksheets

For teachers

Use an "alligator mouth" anchor chart so students remember which way the > and < symbols open.
Have students justify their comparisons aloud or in writing; "23 is greater than 19 because…"
Mix object comparisons with numeral comparisons in the same worksheet to bridge concrete and abstract thinking.
Add a sorting activity afterward where students put 5–10 numbers in order from least to greatest.

For parents and at home

Compare household quantities; who has more crayons, which bowl has more cereal; to make practice concrete.
Use the phrase "greater than / less than" rather than "bigger / smaller" to match math vocabulary.
Connect comparisons to weight, height, or age in your family for real-world relevance.
