Can you tell which object is biggest or smallest? With this muddy game, kids will hop on the mud puddle that shows either the biggest object or the smallest object. Listen closely to the prompt, and remember that the sizes of these objects on the screen are sometimes different than their size in reality. We want to know the biggest or smallest object in terms of their real-life sizes. Talk with your child more about sizes and shapes of objects, and see if they can explain how big each object on screen might be in real life.
