About this worksheet
Six rows of pictures from groups like animals, food, clothes and things that go.
What kids practice
Opposites are pairs of words that mean very different things, like hot and cold or up and down. Categories are groups of things that go together, like animals, food or clothes. Knowing both helps kids learn new words faster, describe things clearly and understand what they read.
Watch for
- Picking a related word instead of the opposite, like "warm" for hot. Ask "What is the most different?"
- Naming things that are related but not in the group, like "milk" for animals because cows make milk.
- Saying "it just doesn't belong" without a reason. Ask what the other three have in common.
It's free to print, with an answer key. See the full opposites and categories guide for 1st grade.
