Here's why you should do it: The technical term is "Conservation of Number" - If they are able to understand that the number is the same in spite of the visual differences once the jars are removed, then "conservation of number" has been mastered. Alright, so he got a little bored during the whole process, but then I did, too, making sure each marble went into the jar. :) He was confident that they were the same all along, but when I pulled them out, he wasn't so sure after all. (But I think he did question himself trying to decide.)
Notice I didn't tell him, "Of course they were the same because you said it the entire time", but I let him prove and discover on his own by counting that they were indeed the same. This is an important step because it solidifies in a concrete way what he saw and then believed once the jars were revealed.
Go through your recycling and try this out! :)
Here's why you should do it: It helps increase concentration and coordination and teaches one-to-one correspondence. (and toddlers love repetition so your kiddo might do it over and over and over and over again and you might get ten minutes peace - just change out the objects periodically!)
Here's why you should do it: To help increase concentration levels, fine motor skills and hand-eye coordination.
