Build the key vocabulary of Classifying Organisms with this printable picture flash card set for Grade 4 science, aligned to Virginia SOL 4.3. It covers 12 essential terms, from Classification and Plant to Insect. Each term comes as a picture-and-word card and as a picture card with a clear, full-sentence definition, and two labeling worksheets let students show what they know.

What students practice

• Classification: Classification organizes organisms into groups using shared characteristics, helping scientists compare living things and communicate about their relationships.
• Plant: Plants are organisms that usually use light to make food and have cells with walls that provide support.
• Animal: Animals obtain food by eating other organisms or their materials, and most can move from place to place during some life stage.
• Fungus: Fungi obtain nutrients by absorbing them from other materials, and they do not make their own food through photosynthesis.
• Vertebrate: A vertebrate is an animal with a backbone, including familiar groups such as mammals, birds, fish, reptiles, and amphibians.
• Invertebrate: An invertebrate is an animal without a backbone, such as an insect, spider, earthworm, snail, or jellyfish.
• Mammal: Mammals are vertebrates with hair or fur, and their young receive milk produced by a parent as they grow.
• Bird: Birds are vertebrates with feathers, beaks, and wings, and they hatch from eggs even though not all birds can fly.
• Fish: Fish are aquatic vertebrates that typically breathe with gills and use fins to move and control their bodies in water.
• Reptile: Reptiles are vertebrates with dry, scaly skin that breathe with lungs, including snakes, lizards, turtles, and crocodilians.
• Amphibian: Amphibians are vertebrates with moist skin, and many change from aquatic young into adults that can use land and water.
• Insect: An insect is an invertebrate with six legs and three main body sections, often with antennae and wings.

How to use it in class

1. Print the color cards (or the black-and-white set to save ink), cut them apart and laminate them to reuse.
2. Introduce the words with the picture-and-word cards, then use the definition cards to talk about what each term means.
3. Play quick games: show a picture and ask for the term, read a definition and ask which card it matches, or sort the cards into groups.
4. Use the labeling worksheets as an exit ticket, homework or review, and check them with the answer key.
5. Put the cards in a word wall or science center for independent practice.
