10 Days of Holiday Mystery Markdowns

I've linked up with Janet (FishyRob) from Teacher Times Two to share a little holiday cheer! I'm a little late to start, so my markdowns will be for 10+ days, rather than 12:)

Every day until Christmas I will mark down one item in my store, up to 50% off!  You might need to snoop around my store to find the marked down item...but it shouldn't be too difficult to find.

Decimal Problem Solving

I like to do a lot of problem solving with my students, usually having them work together so that they can model for each other and share/listen to each others' thinking. For the past two days, most of my math classes have been working on "Party Planning," which is the problem pictured here.  Students worked with one or two partners, to come up with combinations of foods that "Reggie" could buy for a party.

I love listening to the kids' conversations as they work on things like this - "No one eats pretzels," "I'd choose candy and chips over pretzels," and so on.

The students had a few important questions for me, though, as they were pretty serious about this planning:  Is this a "regular" party or like a sleep-over party, because the kind of food would depend on how long the party is."  "How big is the container of ice cream?"  "How big is the bag of candy?" And then there were a few other ideas, that made me realize I needed to add some more detail/requirements, like the students who said, "Let's just get 50 bottle of soda!" Or the students who decided that 5 fruit trays would be a good plan (even though Reggie wanted a variety of food items).

So, I revised the problem, which you can download, if you'd like. This page is part of a larger product that includes several other problem solving pages, as well as a Footloose task card activity.

Decimal Operation Help!



We've been spending a bit of time on decimal operations. I have five math classes, and in four of the five, our work with decimal operations has gone pretty well. There are a few students who are still mixing up their rules - when to line the decimal point up and when not to. When to count the digits behind the decimal points and when not to. However, in the fifth math class, there are many students who are not "getting it," even though did work with decimal operations last year. Part of the not getting it, I believe, is due to the fact that they don't actually look at their answers and think about whether or not they make sense. For example, many students will take a problem like 18.9 - 8 and get 18.1 as the answer....and they don't notice that it doesn't make sense to take 8 from 18 and still have 18 left. We've had discussions, gone through so many examples, and they've practiced the operations individually (and did very well when adding and subtracting were the only operations we were practicing). But when we put adding, subtracting, and multiplying together, forget it! Everything flies out the window! (We haven't done division yet, but I find that this doesn't normally mess them up like adding/multiplying confusion does).

Since I feel at somewhat of a loss, I made a new notes sheet for the to use as a reference. They already have a fold it up in their Fold It Ups books, but it seems that they don't use it (or don't understand it?) So, this new one is more "visual." It looks a bit busy to start with, but I'm hoping that the arrows and different shapes will help to trigger something in their memories when they try to remember certain rules (until their number sense gets a bit stronger).

We'll see if this helps!

Anyone have any special ways to help struggling students to keep these operations straight?

Workin' on it Wednesday

I've been working on a few things:

1) writing more challenging problems for ratios/proportions unit
2) cleaning/organizing at home
3) trying this pumpkin growing idea that I saw on Pinterest!
(I bought the pumpkin over two weeks ago but took until today to spend 5 minutes to cut it and add dirt!)  I want to see if the seeds really will grow (before the pumpkin rots....stay tuned:)


What are you working on? Link up  below!
