Day 103 of 150 Spatial Difficulty 6/10
A short mental-rotation drill lifts kids' arithmetic
Quick answer
A short mental-rotation drill lifts kids' arithmetic. Today's question (Spatial training transfer to math) asks about a finding from Cheng, Y.-L., & Mix, K. S. in 2014. The correct option is Improved performance specifically on missing-term arithmetic problems (e.g., 4 + __ = 9) — full explanation, primary source, and glossary cross-links below.
Today's question
Cheng and Mix (2014) gave 6–8-year-olds either a 40-minute mental-rotation training or a control task. On a later math test, the trained children showed:
Reveal the answer and explanation
Correct: B — Improved performance specifically on missing-term arithmetic problems (e.g., 4 + __ = 9)
Cheng and Mix (2014) found that a brief mental-rotation training produced immediate gains in children's missing-term arithmetic — problems whose solution involves rearranging the equation as if rotating its parts. The result is one of the cleanest demonstrations of transfer from spatial training to a non-spatial-looking math task. It supports a broader thesis that spatial reasoning underlies aspects of arithmetic and algebra typically taught as purely symbolic, suggesting low-cost spatial interventions could be a useful classroom supplement.
