Introduction: The PreK Predictor
Longitudinal study (Rittle-Johnson et al., 2015):
- 200 PreK students (ages 4-5)
- Tested: Pattern recognition ability (AB, AAB, ABC patterns)
- Followed: Same students through 3rd grade (age 8-9)
- Measured: 3rd grade standardized math achievement
🎯 Shocking Finding
PreK pattern ability predicted 3rd grade math scores with r = 0.64 correlation
Translation: A student who excels at patterns at age 4 will likely excel at math at age 9.
⚡ Even More Shocking
Pattern recognition predicted math better than:
- Number sense (r = 0.52)
- Counting ability (r = 0.48)
- Shape recognition (r = 0.43)
💡 Implication
Pattern practice ages 3-6 may be THE most important math readiness activity.
Why Patterns Matter for Math
Patterns Are the Language of Mathematics
📐 Elementary Math is Patterns
- Skip counting: 2, 4, 6, 8, 10... (AB pattern: +2, +2, +2)
- Multiplication tables: 3, 6, 9, 12... (repeating addition pattern)
- Even/odd: 2, 4, 6, 8... vs 1, 3, 5, 7... (two alternating sequences)
- Place value: Ones, tens, hundreds (×10 pattern)
- Fractions: 1/2, 1/4, 1/8, 1/16 (÷2 pattern)
🎓 Advanced Math is Patterns
- Algebra: x, y, x, y, x, y... (variable patterns)
- Functions: f(1)=2, f(2)=4, f(3)=6, f(4)=8 (doubling pattern)
- Sequences: Fibonacci (1, 1, 2, 3, 5, 8, 13... each term = sum of previous two)
- Calculus: Derivatives follow power rule pattern (d/dx[x^n] = nx^(n-1))
Warren & Cooper's discovery (2008): Students who master pattern generalization by age 7 show 2.1× faster algebra acquisition in middle school.
The Eight Pattern Types (PreK to Grade 5)
Level 1: AB Pattern (Ages 3-4, PreK)
Structure: Two elements alternating
Examples:
- Colors: Red-Blue-Red-Blue-Red-Blue
- Shapes: ●○●○●○
- Sounds: Clap-Stomp-Clap-Stomp
Cognitive demand: LOW (simplest pattern)
Math connection: Foundation for alternating sequences (even/odd, +/−)
Success rate: 82% for 3-year-olds (McGarvey, 2012)
Level 2: AAB Pattern (Ages 4-5, PreK-K)
Structure: Two of A, one of B, repeats
Examples:
- Colors: Red-Red-Blue-Red-Red-Blue
- Shapes: ●●○●●○
Cognitive demand: MODERATE (must track repetitions)
Math connection: Grouping concept (2+1, 2+1, 2+1)
Level 3: ABB Pattern (Ages 4-5, K)
Structure: One of A, two of B
Examples: Red-Blue-Blue-Red-Blue-Blue
Math connection: Inverse of AAB (prepares for commutative property: 2+1 = 1+2)
Level 4: ABC Pattern (Ages 5-6, K-1st)
Structure: Three distinct elements in sequence
Examples: Red-Blue-Green-Red-Blue-Green
Cognitive demand: MODERATE-HIGH (track 3 elements)
Math connection: Three-step sequences (hundreds-tens-ones place value)
Level 5: AABB Pattern (Ages 6-7, 1st)
Structure: Two of A, two of B
Examples: Red-Red-Blue-Blue-Red-Red-Blue-Blue
Math connection: Doubling (2×2 structure)
Level 6: AAAB Pattern (Ages 6-7, 1st)
Structure: Three of A, one of B
Math connection: 3:1 ratio concept
Level 7: ABCC Pattern (Ages 6-7, 1st-2nd)
Structure: A, B, then two of C
Math connection: Complex grouping (1+1+2)
Level 8: Growing/Shrinking Patterns (Ages 7+, 2nd+)
Structure: Pattern changes systematically
Examples:
- Growing: 1, 2, 4, 8, 16 (doubling)
- Arithmetic: 2, 5, 8, 11, 14 (+3 each time)
- Geometric: 3, 9, 27, 81 (×3 each time)
Growing Pattern Example: 1, 2, 4, 8, 16, 32... Rule: Double each time (×2)
Cognitive demand: HIGHEST (must identify rule, not just repetition)
Math connection: DIRECT algebra preparation (functions, sequences)
Research (Blanton & Kaput, 2005): Students mastering growing patterns by 2nd grade show 2.7× faster transition to algebraic thinking.
Pattern Recognition → Algebraic Thinking Pipeline
The Developmental Sequence
Age 3-4: Pattern Copying Task: "Continue this pattern: ●○●○___" Cognitive skill: Identify rule, apply repeatedly Status: Not yet algebraic (no generalization) Age 5-6: Pattern Extension Task: "What comes 10 steps later in: ●○●○...?" Cognitive skill: Predict distant term without drawing all Status: Emerging algebraic thinking (mental calculation) Age 7-8: Pattern Generalization Task: "Describe the pattern rule in words" Student: "It alternates circle, square, circle, square" Status: Algebraic thinking (verbal abstraction) Age 8-9: Pattern Symbolization Task: "Use letters to describe: ●○●○" Student: "A-B-A-B, where A=circle, B=square" Status: Formal algebraic thinking (variables represent elements) Age 9-10: Functional Relationships Task: "If position 1 is ●, position 2 is ○, what's position N?" Student: "If N is odd, circle; if N is even, square" Status: Advanced algebra (function notation, conditional logic)
Research Evidence: Patterns → Algebra
Blanton & Kaput (2005): Elementary students (grades 3-5) taught pattern generalization
Intervention: 20 minutes/day pattern practice for 8 weeks
Control group: Traditional math curriculum (no explicit pattern focus)
Result (when both groups reached algebra in grade 7):
- Pattern group: 87% proficiency on algebraic thinking assessments
- Control group: 41% proficiency
- Pattern advantage: 2.1× higher algebra readiness
Neuroscience of Pattern Recognition
The Intraparietal Sulcus (IPS)
🧠 Brain Region: IPS (Intraparietal Sulcus)
Location: Parietal lobe
Function: Number sense + pattern detection
Development Timeline:
- Age 0-3: IPS develops through sensory patterns (rhythms, visual sequences)
- Age 3-6: IPS connects to language areas (verbalize patterns)
- Age 6-9: IPS integrates with frontal cortex (abstract pattern rules)
fMRI evidence (Cantlon et al., 2006):
- Children doing pattern tasks show IPS activation
- Same IPS regions activate during arithmetic
- Interpretation: Pattern recognition and math use shared neural substrate
Pattern Practice Strengthens Math Networks
Jolles et al. (2016) study:
- 6-year-olds practiced patterns 15 min/day for 12 weeks
- Pre/post fMRI scans
- Finding: IPS gray matter increased 8% (structural brain change)
- Transfer: Math fact fluency improved 34% (despite no direct arithmetic practice)
Implication: Pattern practice literally grows the math brain.

- Growing patterns: 1, 3, 6, 10, 15 (triangular numbers)
Time: 20 min/day, 5×/week
Differentiation Strategies
🔧 For Struggling Pattern Learners
Diagnostic: Student fails AB pattern
Intervention:
- Reduce to A pattern (red-red-red-red) → "All the same" (1 week)
- Introduce ABB pattern with high contrast (●●○●●○) (2 weeks)
- Return to AB with mastery expected (week 4)
Concrete support: Use physical objects + verbal labels ("Red, blue, red, blue")
🚀 For Advanced Pattern Learners
Extension activities:
- Complex patterns: AABBC, ABCABC, AABCCB
- Two-attribute patterns: Red circle, blue square, red circle, blue square (color + shape)
- Numeric patterns: Fibonacci, prime numbers, powers of 2
- Create/decode: Student creates pattern, partner identifies rule
🌟 For Students with Autism
Research (Hume et al., 2012): ASD students often EXCEL at pattern recognition (visual systemizing strength)
Instruction:
- Visual patterns preferred over auditory
- Predictable structure = reduced anxiety
- Use special interest (trains, dinosaurs) as pattern elements
Success rate: 87% of ASD students master complex patterns with visual supports
Assessment Guidelines
PreK-K Benchmark Mastery: 80%+ accuracy on AB, AAB, ABB patterns Timeline: End of kindergarten year 1st-2nd Grade Benchmark Mastery: 80%+ on ABC, AABB, growing patterns (arithmetic sequences +2, +5, +10) Timeline: End of 2nd grade 3rd-5th Grade Benchmark Mastery: Generalize pattern rules verbally + symbolically Example: Pattern: 5, 8, 11, 14, 17 Student describes: "Add 3 each time" Student writes: "Start at 5, then +3, +3, +3..." Advanced: "Term N = 3N + 2" Timeline: End of 5th grade
Common Misconceptions
❌ Misconception: "Patterns are just for preschool"
False: Pattern recognition develops continuously through grade 12
Evidence: Advanced algebra (sequences, series) = complex pattern analysis
❌ Misconception: "Patterns are separate from 'real math'"
False: Patterns ARE the structure underlying all mathematics
Research: Students with poor pattern skills struggle with:
- Multiplication (array patterns)
- Fractions (fraction patterns: 1/2, 1/4, 1/8)
- Algebra (function patterns)
⚠️ Misconception: "Smart students naturally see patterns"
Partially false: While aptitude varies, pattern recognition is TEACHABLE
Research (Rittle-Johnson et al., 2015): Explicit pattern instruction improves scores 41% over control (no instruction)
