The CVC Tri-Blocks Tub gives early learners an interactive way to explore how individual sounds combine to form words. The 90-piece set uses connecting blocks that can be twisted to change the beginning, middle or ending sound, allowing children to quickly create and compare different CVC words. A clear colour system distinguishes initial consonants, short vowels and final consonants, helping students isolate each phoneme and recognise its position within a word. Designed for ages 5–8 years, the blocks can be used independently or paired with CVC Builders Activity Cards for guided practice.
Applications and Use
 • Construct consonant-vowel-consonant (CVC) words by connecting three blocks.
 • Twist individual blocks to investigate how changing one phoneme creates a new word.
 • Practise isolating initial, medial and final sounds.
 • Explore short vowel sounds and their role within CVC word patterns.
 • Pair with whiteboards so students can record and read the words they create.
 • Incorporate into literacy rotations, intervention sessions or peer activities.
 • Combine with CVC Builders Activity Cards for visually guided practice and additional challenges.
Features
 • 90-piece Tri-Blocks set supplied in a convenient storage tub.
 • Connecting design allows blocks to slide together and rotate independently.
 • Dark blue initial consonants, red short vowels and light blue final consonants provide clear visual differentiation.
 • Tactile format reinforces letter-sound relationships through physical manipulation.
 • Allows students to experiment with different sound combinations and observe changes between words.
 • Suitable for independent exploration, paired learning and teacher-led instruction.
