Target early sequencing and comparison skills with this engaging ABLLS-R B25: Seriation resource! This hands-on activity is designed to help learners organize items along a continuum by size, color intensity, and quantity, making it perfect for ABA sessions, special education classrooms, and early learners.

This resource includes 3 different seriation tasks:

• Size (e.g., large car → small car)
• Color (e.g., light yellow banana → dark brown banana)
• Quantity (e.g., cookies with varying numbers of chocolate chips)

Each task includes 20 cards total (5 sets of 4 cards), giving you plenty of opportunities for repetition, generalization, and skill building across multiple exemplars.

To support independence and visual learning, this set also includes sorting strips with clear labels:

• Smallest → Largest
• Lightest → Darkest
• Least → Most

Plus, blank strips are included if you prefer to fade prompts or assess true mastery without visual cues.

What’s Included:

• 60 total task cards (20 per category: size, color, quantity)
• 3 labeled sorting strips (size, color, quantity)
• 3 blank sorting strips for flexible use

Why You’ll Love It:

• Aligns directly with ABLLS-R B25 (Seriation)
• Promotes critical thinking, visual discrimination, and sequencing skills
• Perfect for discrete trials, independent work, or centers
• Easy to prep and reuse (just print, laminate, and go!)

This resource makes teaching seriation fun, structured, and visually clear—helping your learners build foundational cognitive skills with confidence!
