Build your number-shape peg list

Assign a vivid concrete image to each digit 1–10 based on the digit’s visual shape.

Why it works

Concrete, distinctive images recruit the brain’s rich visual-spatial memory system rather than its weaker verbal rote system. Pre-loading the pegs means each future memorization task requires only one encoding step (link new item to peg), not two, which reduces cognitive load at recall time.

How to do it

1. For each digit 1–10, pick an image whose shape mirrors the numeral: 1 = candle, 2 = swan, 3 = handcuffs, 4 = sailboat, 5 = hook, 6 = elephant’s trunk, 7 = cliff, 8 = snowman, 9 = balloon on a string, 10 = bat and ball.
2. Make each image as vivid and personally meaningful as possible; your own associations beat generic ones.
3. Drill the list until peg images surface instantly when you say the digit — before using them for real material.

Evidence

Pegword methods have been tested in educational research, primarily with older adults and vocabulary learning, with positive results. The underlying mechanism — imagery-based elaborative encoding — is robustly supported. (observational)

Most controlled studies use simpler pegword variants. Lorayne’s full system is practitioner-validated rather than independently RCT-tested.

Common mistake

Choosing abstract or interchangeable peg images (e.g., two different types of balls for different digits) so retrieval requires effort to distinguish them.
