School supplies: calculators: the amazing Staples BD-6108 scientific calculator

Tutoring math, calculators are always interesting. The tutor mentions a great find at Staples.

On a clearance rack at Staples yesterday I found the BD-6108 scientific calculator for $3.97.

I can’t remember seeing the BD-6108 before, but I just opened it from the carton and it’s fantastic. It does everything my high school students typically need, except graphing. Since graphing calculators may not be allowed for some tests, students need a plain scientific one for everyday use. The Staples BD-6108 is even more powerful than needed.

I love the Staples BD-6108, but perhaps it’s not for everyone, since it’s reverse-entry, which means you enter the number, then the function. Most students seem to prefer forward entry, which essentially means you enter an operation the way you would write it.

To me, a surprising feature of the BD-6108 is its quadratic equation solver. I can’t remember seeing a simpler one, and here’s how to use it:

  1. Let’s imagine you want to solve 3x^2 + 13x – 10 = 0.
  2. First, press MODE 7.
  3. You’ll see the prompt for a. Key 3, then DATA.
  4. You’ll see the prompt for b. Key 13, then DATA.
  5. You’ll see the prompt for c. Key -10, then DATA.
  6. The first solution will appear: 2/3.
  7. Press DATA to see the other solution: -5.

For everyday, nonspecific calculations, the BD-6108 must be in MODE 1: it’s important to remember to return to MODE 1 after doing something else, such as using the quadratic solver.

Inside its packaging the BD-6108 contains a folded-up manual. Read it, front and back; it won’t take long.

I hope to share other school supplies discoveries in future posts:)

School supplies: the Five Star Pencil Pouch by Mead

Tutoring, you encounter school supplies. The tutor talks of one he recently adopted.

Let’s imagine the situation in which a person works in one place, not having to move their work or materials. Furthermore, let’s imagine they have their own workspace that they don’t share. That situation may not mandate using a pencil case.

If, on the other hand, the person needs to transfer their materials to and from work, or needs to store theirs among other peoples’, then they need to contain their pencils, pens, etc: a pencil case is probably indicated.

Needing to pack some school supplies for a trip, I went to a box where we store our kids’ old and new ones, looking for a pencil case. I found a Five Star Pencil Pouch by Mead.

The pouch’s bright colors – pink with other pastels – caught my attention, as did its binder rings. I get that fastening the pouch in a binder’s rings might be useful to prevent loss.

After a few minutes I noticed that the pouch has not just one zipper pocket, but two: one adjacent the rings, and the other opposite, facing outward. If the pouch is locked in a binder, you can access supplies from the outer pocket without flipping the binder open. Additionally, you can put pens in one pocket, pencils in the other, or so on. The second pocket is an organizational feature I admire.

The tag says ACCO Brands, of Dayton, Ohio, but mentions Hilroy as well. The name Mead appears on the pouch itself. Hilroy and Mead I’ve known forever.

I adopted the pencil pouch:)

School supplies: mechanical pencils vs wooden ones

Tutoring math, you see the pencils students use. The tutor makes some observations.

I’m a fan of mechanical pencils:

  1. You needn’t sharpen them.
  2. One will last for weeks, months, or even longer, depending on usage.
  3. You can retract the lead when the pencil is not in use.
  4. There are many, many kinds to choose from.

You can buy a nice mechanical pencil and then lead refills for it, but packs of disposable ones can be great. I’ve typically used disposable Bics or Staples ones…there are many other kinds available that have cute features.

Last year, in grade 9, my older son started using mechanical pencils; he prefers them now. My younger son, starting grade 8 this year, still prefers wooden ones. They both share that having your own sharpener, if you use wooden pencils, is preferable.

Wooden pencils have a great feel when they’re sharp. However, they don’t stay sharp on their own. Hence, mechanical pencils seem more practical (to me, anyway).

Starting with a mechanical pencil, a student may be a bit heavy-handed, so a 0.7mm pencil is probably best. However, after getting used to it, the student might try a 0.5mm one – the finer lead appeals to some people.

PS: Although a pencil typcially comes with an eraser on it, a dedicated eraser is needed.

I hope everyone’s enjoying their last day of summer vacation:)

School supplies: stick pens

Tutoring, school supplies are ever-present. The tutor brings up stick pens.

Stick pens (ball-point with a cap) are perhaps my favourite kind. One reason I like them is they don’t make noise. Plus, they’re cheap enough that it makes sense to buy a box of them, then leave a few here and a few there in places you might need one.

Today I picked up three of unknown age that I found at various places in the house. The PaperMate Write Bros, the Staples generic, and the Bic Round Stic all write nicely on cue. So I guess any of these seems good to me.

School supplies: pens

Tutoring, you see all manner of school supplies. The tutor mentions two kinds of pens.

I love good pens. By “good” I mean they write well.

There are a few classifications of pens, from my point of view: stick, click, and other (fountain, for instance).

In the case of click pens, there are a couple of kinds I like. If you like PaperMate, the InkJoy might appeal to you. For Bic fans, there’s the Soft Feel.

I like both.

I’ll be sharing more about school supplies.

Studying and writing: color stimulation

Tutoring, colour choices of supplies, and even the room, can influence learning patterns. The tutor shares a couple of discoveries about environmental colour.

We all have items that we like because of their colour. Perhaps it’s a pair of boots, a purse, or a phone case. When something is attractive, we like to use it, so are more drawn to activities in which we will.

In the context of working or studying, colour cues can affect peoples’ performance. Red seems best to stimulate attention to detail. Blue, on the other hand, more likely brings forth a worker’s creative side.

Interestingly, not much of the key colour is needed. The presence of a red book on the desk, or some blue cue cards lying there, might be enough – as long as they’re not present at the same time.

Coincidentally, or maybe not, the dictionary I use most often is indeed red. By contrast, the screen cues where I write posts are blue.

School Supplies: A tutor’s point of view

Last year, listening to French radio, I heard a surprising report:  school supply shopping is the second most stressful occasion for a great many parents, second only to Christmas shopping.

If that’s true, it doesn’t need to be.  What’s more, I can explain why:

1) With Christmas shopping, you’re not told what to get – whereas with school supply shopping, you usually are.

2) While, with Christmas shopping, there is a deadline, there really isn’t one in the same way when it comes to school supply shopping.

I’ve heard that a lot of people fear the expense of back-to-school shopping.  I can’t comment on the other dimensions of it (clothes, for instance), but I can tell you this:  school supplies don’t have to be (that) expensive.

In front of me I’ve got two big-box store flyers from Friday’s paper.  I’ll admit that if you have to shop today, you might pay around $15 for a zipper binder (of course, you can pay a lot more if you want), then another $15 or more for a school bag.  (This is all before tax.)

Coloured pencils, if you need those, might run around $2.50 to $6.00.  Buy a good name – not cheap ones.  When you’re a tutor, you see a lot of school supplies.  I’ve noticed that many kinds of coloured pencils – especially cheap ones – don’t hold a sharp point.  You don’t want your kid to be stuck with coloured pencils whose leads keep breaking.  Ask what the good names are.  I use Staedtler, but there are other good ones around.  I’d guess a name like Hilroy would be pretty trustworthy – although I’ve never tried their coloured pencils.

For just normal pencils (rather than colour), I prefer mechanical rather than wood.  Get 0.7 leads – they last longer and break way less often (as opposed to 0.5).  A twelve pack of Bic 0.7 plastic pencils will cost maybe $4.  If they don’t get lost, your kid probably wouldn’t use more than half of them the whole year.  Pens are even cheaper than pencils – unless you want to pay more for something special.

One note, though, about mechanical pencils:  you can’t get them for most kids until they’re in grade 5 or later.  The reason is that the kids just play with them.  If your kid is earlier than grade 5, you probably want wooden pencils.

Erasers:  get white ones.  Staedtler is one kind I use, but most white erasers are pretty good.  At one place, they’re on for less than a dollar apiece right now.  If it’s not lost, one could last you for years.

Paper – both loose leaf and graph – might be the most variably priced item.  You might have to pay a lot on a given day at a given place.  However, my wife says she’s seen 150 sheets of loose leaf for less than a dollar recently. If you’re paying more than that today, you should probably look elsewhere.  Graph paper is usually more – you might have to pay 3 or 4 dollars for around 100 sheets – but you can sometimes get it for a lot less.  Kids don’t usually use much of it, anyway.

Markers, if you need them, might be around what coloured pencils cost.  A ruler you can get for less than a dollar.  A scientific calculator shouldn’t cost more than $15.  I know I could get a good one for less.  The less fancy, the better.  As long as it has sin, cos, and tan on it, as well as square root, you’re probably pretty safe.  Of course, you shouldn’t need to buy a new calculator every year.

There are other odds and ends, but let’s make a rough total of the items I’ve mentioned.  You might be looking at around $60 to $75 before tax.  You could do better, depending on where you live and how much hunting you’re willing to do.

Where I live, some stores have school supply lists right at the front entrance.  You can find your kid’s school and grade, then pick up a list of supplies.

If your kid goes to the first day of school with just a few pencils and pens, some paper, a binder, a calculator, and the coloured pencils, they’ll probably be all right.  When they get home, they can tell you what they’re missing, and you can get the rest that night.

One final point:  Look for school supplies again in a month.  Watch the prices go up and down.  Eventually you’ll probably be able to get almost everything cheaper than you can today.  Stock up when it’s cheap.  Ask your kid what works and what doesn’t – and why.  If you familiarize yourself with school supplies, you’ll be on top.  Like most things, they’re best to buy before you need them.

Good luck!
