Innovation in children is typically studied by examining their capacity to independently create tools to solve problems. However, it has been argued that innovating requires more than creative problem-solving
it is essential that the future utility of a solution is recognized. Here, we examined children's capacity to recognize and construct a tool for future uses. Experiment 1 presented fifty-five 3- to 5-year-olds (28 girls) with a future-directed variation of a task in which children had to make a hook to solve a problem. When given a tool construction opportunity in anticipation of returning to the task, only 5-year-olds chose to make a hook-shaped tool more often than expected by chance. Experiment 2a assessed ninety-two 3- to 7-year-olds' (48 girls) capacity to construct a tool with both present and future utility in mind. Specifically, they needed to make a tool long enough to not only poke a ball from a short tube in the present but also poke a ball from a longer tube in the future. Older children tended to construct longer tools and were more likely to do so in this situation than in a follow-up control study (2b,
