Today's Topic: Comparative Size*
Supplies (these are just for inspiration--look through your own supplies to see what else might work):
Nesting toys (or a set of nesting bowls)
printable nesting dolls (great examples here and here)
bouncy balls in a variety of sizes
Small smaller smallest / Fletcher, Corina
After I read the book: In the first class of the day, I just quickly explained the activities and we moved right to the tables and we got a lot of this sort of action:
What the kids actually did once we went to the tables:
organized things from smallest to biggest
a super long caterpillar
"it's wearing a hat!"
Adult Challenge of the week: Watch! Rather than worrying about whether your kid lines up the objects exactly in size order (or lines them up at all), just watch and observe how they interact with the materials provided. They'll be learning about SOMETHING no matter what they choose to do!
--The most effective examples of this concept were the nesting objects. Those were the things that looked very different if you arranged them in order vs. out of order. If you can get some actual nesting dolls or any other nesting or stacking toys, do so!
--While it's pretty easy to find the biggest and smallest in a set, the fine-tuning of the middle ground is often a bit more challenging. You might want to address that during the instructions.
Variations to try:--If everyone takes off their shoes in your library programs, have them line up shoes by size.
--Grab a bunch of different sized books off your shelves and have kids line them up in order (you can have a related conversation about lining the books up according to how many pages or how many words are in them too!)
--Here are some more ideas!
--And more ideas!

*Note: While I randomly chose the term "comparative size," it seems that this concept is more formallly known in math education circles as "seriation" or "ordering/sequencing by size." For more information about teaching children about size and measurement, watch this short video.
