Comparing Quantities While Talking

For 5- to 7-year-old children

In this study, your child will be introduced to a character named Wally the Bear. They will choose which of two glasses of juice they think will taste the same as Wally the Bear’s juice. If your child cannot click on their own, you can enter their response by clicking on their choice. Sometimes, your child will also be asked to say the word “the” while making their choices.

Proportional reasoning is important to our everyday lives, but people make a lot of mistakes when evaluating ratios, especially when the ratio in question is broken up into parts. This study is looking to explore the causes of this difficulty.
