Money string of exercises

[Christi]

Ok. So I have a string of money exercises in mind.

All would need images of real coins.

1 - identify coin, order smallest to largest, random head or tails

2 - identify coin, in line, random order 3 - identify coin, scattered

there's more... will be updating this

Hey @Christi , I'm looking for more exercises to work on, and I could try creating this one. Do you know where I could find pictures of coins to use?

[Christi]

Let me grab some. I was thinking of just doing a search... ;-)

[Christi]

How about using this: http://imulus.com/blog/wp-content/uploads/2009/03/american-coins.jpg

I'd go with clipping the images and use them all from this. I can snip and attach when I get home.

[Christi]

So, @ifingerson the thing with this is it's more or less a request from teachers at my school and a lot of the kids (even the older ones) need to work on coins, both recognition and knowing values through being able to make change. If you're up for it, we can discuss the types of things that would work and what some of my vision was with this. Basically, something functional that would help get students to the point where they could survive independently.

I don't yet know how to create anything interactive, but I'm sure I could figure it out, becase it wasn't that long ago that I didn't even know any HTML. But here are just some ideas of different problem types (probably more than one exercise):

• Shown image of coin, have to name it (multiple choice)
• Shown image of coin, have to give its value (cents or dollars)
• What coin has the following value (multiple choice)
• Ordering coins
• Given a number of coins, have to give the total value.
• Have to make a given value with coins
• Given the name of a coin, have to click on it

All of the coin images would be randomly heads or tails. I'm thinking probably at least 2 exercises for this. How does this look?

And a question: would I just be using the 4 coins: penny, nickel, dime, and quarter, or would I also add things like the 50 cent coin (whatever it's called...) ?

[Christi]

Thinking... so for the youger kids, just the four basics. For the older ones, all types. You've gota good feel for what I'm thinking of. My thinking of breakdown: identifying coins 1 (typical 4) identifying coins 2 (all coins) Money value (small number, basic 4) - depends on ic1 Money value 2 (coins and bills) depends on ic2 Paying for something (need a good name for this) show coins and bills and user has to select right payment Making change - user selects bills or coins based on what was paid by 'customer' and what was owed

Think these are the big ones. When I get home I'll Break down your problem types to how it might work.

I'll also add a few sample questions. It would be great if we could work something up before I present to the teachers of the non-diploma (i.e. functional life skills) although some of this would be good for typical kids.

So for the first one (identifying coins 1), would that incude just names and images, or also values of the coins as well? And what other coins are there besides the 50 cent coin?

[Christi]

Ok.
Identifying coins 1:

problem type 1: show coin (penny, nickle, dime, quarter), Prompt: What coin is shown? Hints: 1. What coin is (describe coin based on image, color, size)? (possible hint: show flip side of coin and say 'The other side of the coin looks like this") 2. This is the coin that is worth cents. 3. final-answer: This is a . textbox for answer. Allow nickel or nickle.

Problem type 2: Show coin. Prompt: This coin is worth how many cents? Hints: 1. This coin is a . 2. final-answer: A is worth cents. integer for answer.

Problem type 3: Show 3 coins. Prompt: Click on the /Click on the coin worth cents. Hints: 1. (for value only) A is worth cents. 2. (or 1 for coin) A is . 3. final-answer: The is the one in the (some color) circle. answer-type will be which coin is clicked - identify coin clicked with a thick blue outline. Don't allow the final answer to let the student get the problem without clicking. Selecting any coin should deselect any others. This may be the hardest since it will need graphie.

Identify coins 2: Same as the above questions with the three extra coins. Half dollar, Susan B. Anthony dollar coin and Sacajawea dollar coin. (Huh, found there's a Presidential dollar coin - see http://en.wikipedia.org/wiki/Coins_of_the_United_States_dollar for some more information on US coins.) One difference, have Problem type 3 show 4 coins instead of 3 (but not 2 of same value)

See #39741, @cbhl made a comment about how they've been staying away from vocabulary exercises, so maybe instead of a text box, it should just be multiple choice.

[ghost]

Whoa, there are a lot of U.S. coins! http://coins.about.com/library/Coin_Identification/bl_identify_us_coins_using_photos.htm

[ghost]

There wouldn't be any copyright issues or anything if I used these, would there? http://www.usmint.gov/kids/teachers/coinCurricula/01centCoin.cfm

[Christi]

Well, this isn't strictly a vocabulary exercise. This is something that comes up in more functional programs. I'd go with textbox rather than multiple choice because with multiple choice it's more multiple guess. The difference between recognition level and recall level in learning - a student may be able to recognize an answer without being able to produce the answer.

The pictures on that site look good and since it's a government site I wouldn't worry too much about copyright. However, the one concern I have is that the coins have the correct proportion. One of the features of the coins are the size.

[cbhl]

@ifingerson I think @petercollingridge had a nice library that would tell you if your spelling was "almost" correct; I think that if we used it we could argue that a vocabulary exercise for coins would be justifiable in the US market.

That said, any coins-based exercise would be difficult to localize -- for example, in Canada, we also have a one-dollar coin (colloquially known as a "loonie", because of the loon on the back), and a two-dollar coin ("toonie", portmanteau of "two" and "loonie"). If I recall correctly, there are other terms for coins in other English-speaking locales (e.g. UK), let alone internationally. I wouldn't let that discourage you from building it -- it's just something to be aware of.

With regards to making change / paying for something exercises, it may or may not be useful to copy the style of interface used in understanding_decimals_place_value.html.

[petercollingridge]

@cbhl Not me. I think you may be thinking of @davemajor and this exercise: https://github.com/Khan/khan-exercises/pull/39741. I agree that this would definitely be hard to localise. I suppose it might be worth my learning to identify US coins.

[ghost]

Yes, I have been wondering about the internationalization of this exercise. I agree that even for non-U.S. residents it would still be helpful to be familiar with U.S. coins, but I'm also thinking the other way around: maybe there should be exercises for coins from other countries, also. European coins, Chinese coins, etc. Maybe also converting between different currencies, such as dollars and euros, given the current conversion rate. I don't know, just some ideas.

[sophiebits]

I don't think we'd want to merge this in, partly because of localization problems and partly because there's no place for it on the site.

Conversions given conversion rates could be fine as long as no knowledge specific to one currency is needed.

[Christi]

Rats. This was one that had been noted was missing for students in programs like the lower functioning group at my school. Although, the limited use in a world setting was a thought that crossd my mind
