4.NBT.1 - Place Value & Power

Whew! This week has been crazy. My kiddos have been hard at work learning about how a digit's place affects its value. I think in our minds we, as adults, know that the 3 in the tens place is worth 10 times as much as a 3 in the ones place, but getting my fourth graders to understand this has been grueling! Thanks to a couple of WONDERFUL resources (mainly Blair Turner's Interactive Notebook) my students finally got the idea!

My school uses a great website - www.MobyMax.com - free to teachers for a basic account. I assigned my kids this benchmark for homework and was able to check their progress around 10 pm (when I knew their homework should be done and they should be in bed). I saw that they were struggling with multiplying by 10 or 100 and multiples of 10 and 100. So, before we even made it to class the next day I had a set of task cards created, printed, and waiting for them. I've spent the weekend tweaking & adding to the set to add to my little store. Enjoy!

Mystery Science Lab - A Little Off Topic from My Usual Math Posts...

Ten years! Today marks the tenth year I've held Mystery Science in my classroom. I look forward to this activity every year and I talk it up at our Meet the Teacher & the first day of school. The kids came into school today READY for our first science lab.

The kids love the labs because they're a bunch of mini-exploration activities that require them to use four of their senses (no tasting!) to describe the world around them. Some have right answers and some are completely open. I love the labs because they really let me see the kids in action for the first time each year. Who works well with who? Who tends to isolate him/herself from the others? Is the "new kid" making friends? Can the class follow directions and do they know how to handle lab materials?

A couple of things I  noticed today - they respected the "keep the lab volume at a manageable volume" rule! Yes! Let's celebrate! I love doing science labs, but I dread them if I have kids/groups that feel they have to talk over each other. And, even better, my kiddos really respected the lab materials. I've got some things in our lab that are quite old - like the birds' nest my mom found back when I was in college (yep, that makes it older than my fourth graders). They used their hands to very gently touch it - exactly as I asked them to. :D
