We present Paper Ladder, a low-cost, light-weight, and paper-based variant of the Sticky Ladder rating scale to collect children's product preferences in user studies. This paper version revamps the original, effective but arguably impractical evaluation method by making it more accessible to researchers. In this paper, we show its potential with preliminary results from a pilot study, where 45 grade-2 children used a Paper Ladder to rate their preference for different types of correctness feedback in a math app. Results suggest that Paper Ladder could be an effective and valuable instrument for conducting user studies with young children.
