Math Excuses


A while back one of my readers and top commentators sent me a picture of a clock, knowing that I would find it amusing. Here it is:

9 Clock

(Added 9/26/2013: In the comments to this post, you will see that several of my sharp readers have "done the math" and determined that there's a problem with the math at the 5:00 position. That's the picture that was sent to me, so I'll just have to leave it. You can see their corrections in the comments section of this post.) 🙂

It reminded me of a picture of a clock I featured in a post called History of Math Teaching in the US. In that post I related that each year now I have at least one student who does not know how to tell time with an analog clock. As we face learning time telling again in my beginning languages classes, I'm going to continue to keep analog clocks before my students' eyes, but much simpler than the clock above. 🙂

As I have further contemplated why students do not do well with mathematical concepts, I wondered if, for some, it's simply because they don't do their homework. Today's post is a list of the top ten excuses students give for not doing their math homework. I'm not mathematical enough to understand the humor in some of these, and I even did my homework, always!

Top Ten Excuses For Not Doing Math Homework

1. I accidentally divided by zero and my paper burst into flames.

A Short Test


This week my first-semester German and first-semester French students are having their first test of the semester in my classes. In light of that, I thought I'd post a little test for my blog readers. Just five questions — it'll be a breeze for you. After all, it's in English!

IntelligenceTest

Please answer each test item before scrolling down to see the answer.

Okay, let's find out how attentive you are when taking tests….

First Question:
You are participating in a race.
You overtake the second person.
What position are you now in?

Answer:
If you answered that you are first, then you are…
absolutely wrong! If you overtake the second person, you take his place, so you are now in second!

(Try not to mess up with next question, okay?)

Faulty Conclusions


Bad Math Conclusion

Why do we have a tendency to reach faulty conclusions? The reasons are varied and numerous. They include faulty information, incomplete information, preconceived ideas, taking too little time to analyze the information well, and poor skills in logic, among many others. In math classes we have the opportunity to develop logical thinking, but as shown in the picture above, we still often reach illogical conclusions.

Today's post looks at several examples of faulty conclusions. The first is is very short:

A woman reported, "The bishop came to our church today, but I don't think he was a real bishop. He never once moved diagonally."

Children’s Letters to God


Last evening in the service on campus, Rand Hummel read some letters that children have written to God. Being around our grandchildren has reminded us of how guileless children are. They say what's on their minds with innocent truthfulness.

I did some searching in my files and am sharing the ones someone sent me quite a while back.
