Vocabulary: what you need to know

Vocabulary development involves learning new words and understanding how they are used across listening, speaking, reading, and writing. Students build word knowledge by connecting new words to known ideas, exploring how words relate to one another, and noticing how word forms can change meaning. This includes early morphological awareness, where students begin to notice meaningful parts within words.

Vocabulary learning includes both explicitly taught words and words learned through rich language experiences. Over time, students develop more flexible and precise use of language.

What’s new in the 2026 Curriculum?

The 2026 Kindergarten curriculum places a more intentional and explicit focus on vocabulary development. Within Overall Expectation A1, word learning, along with grammar and sentence structure, is taught systematically as part of early reading instruction, clearly positioning vocabulary alongside phonemic awareness, alphabetic knowledge, phonics, and fluency as foundational skills.

Transitioning to vocabulary in Grade 1

Vocabulary development from Kindergarten to Grade 1 grows from structured, teacher-supported experiences such as sorting, categorizing, and exploring word meanings toward increasingly independent strategies. In Grade 1, students build on this foundation by using context, morphology, and semantic features to determine the meaning of unfamiliar words. This progression helps students apply and integrate vocabulary across subjects.

Teaching vocabulary

Effective vocabulary instruction in Kindergarten blends intentional teaching with language-rich daily experiences. Educators introduce and revisit meaningful Tier 2 words during read-alouds, discussions, and lessons, helping children understand word meanings, word parts, and how words can change depending on context. Modeling and repeating new vocabulary throughout the day helps deepen children’s understanding.

Vocabulary grows even further through meaningful play and exploration. Daily interactions, storytelling, shared reading, and classroom talk give children repeated, authentic opportunities to hear and use new words. When educators create a rich language environment—where children describe, compare, question, explain, and solve problems—vocabulary learning becomes embedded in play. Combining explicit instruction with repeated exposure builds a strong foundation for early reading, writing, and communication.

Assessing vocabulary

Vocabulary in Kindergarten is assessed through ongoing observation. Educators gather evidence during play, conversations, shared reading, and small-group learning to understand how children use and apply new words. They look for children’s ability to explain word meanings, use Tier 2 vocabulary, make connections between words, and apply simple strategies such as using context or noticing word parts.

Educators may observe whether children can:

• use Tier 2 vocabulary introduced during instruction
• explain word meanings in their own words
• connect new words to familiar ideas
• notice differences in meaning (synonyms, antonyms, multiple meanings)
• use vocabulary to describe, compare, explain, or solve problems during play
• respond to rich language during read‑alouds
• show growing word knowledge through drawing, early writing, storytelling, or dramatic play

Assessment is documented through pedagogical documentation (e.g., anecdotal notes, photos, videos, oral language samples). This continuous assessment guides instruction by identifying which words to revisit, which semantic categories to explore, and where children may need more support with context clues or word meanings. The goal is to monitor vocabulary as part of the strong oral language foundation needed for early literacy.
