Locker Problem Explanation Reminders

Here are some friendly reminders for your locker problem explanation.

You must explain HOW you solved the problem. This includes telling me, in logical order, what you did to solve the problem. 

After that you must explain, using appropriate math vocabulary, WHY your answer works. 

You must have a visual that helps explain your answer.

Remember to refer to the rubric as you complete your response.

1: Below Expectation	2: Approaching Expectation	3: Meeting Expectation	4: Exemplary
Solution is not presented Student uses a representation that is not appropriate to the problem No steps used in solving are described Math reasoning and concepts are not explained Math vocabulary is not used	A solution is presented Student uses a representation (picture, table, diagram, and/or algorithms) to organize thinking Steps used in solving are described Some math reasoning and concepts are explained Some math vocabulary is used appropriately in explanation	All of the following are present: Correct solution is presented or incorrect solution is presented as the result of a minor computational error Student uses an appropriate representation (picture, table, diagram, and/or algorithms) to organize thinking All steps used in solving are clearly described in logical order All math reasoning and concepts are clearly explained Precise math vocabulary is used appropriately in explanation	All of the following are present: Correct solution is presented Student uses an appropriate representation (picture, table, diagram, and/or algorithms) to organize thinking All steps used in solving are clearly described in logical order All math reasoning and concepts are clearly explained Precise math vocabulary is used appropriately in explanation Students make a connection or interesting observation about the problem Student presents another way of solving the problem and/or presents thoughtful critique of another way

The format below can help you get started with your writing if you become stuck.

1. Summarize the problem: What is the problem about & what did it ask you to do?

a. First I…because…

b. Then I… because…

c. I realized… because…

d. My final answer is...

3. Is there another way to solve the problem?

4. Share any connections or questions you have

HARDINGE, McCOMB, MUNDEN & CO

How do you calculate interest?

Well, let's say that a bank is having 5% interest per year. The more money you give to your bank, the more interest you get. For example, if you deposit $1,000 in the bank for a year, the next year you would have $1,050 in your bank account. It's important to know that the next year, the interest is 5% of 1,050 - not 1,00 anymore. Under this paragraph, it shows a rate table where I calculated 5% of 1,000. 

Another reason you should invest in Hardinge, McComb, Munden & Co!

Normally, when people "save" money, they usually put it in piggy banks or hide money in a box under their bed. But not only Hardinge, McComb, Munden & Co are trustworthy, they also give out 10% interest - which means you gain more money every year your $1,000 is in our keepings. And, not only you can donate more money to our company, your interest can grow even BIGGER if the size of your money gets larger!

Isn't that much better than sticking cash under your bed, waiting for it to get dusty and perhaps even mold?

Umm, what else are the benefits of having only $100 or $50 per year?

You must be thinking that you only gain 5% of your original balance each year. Well, you're WRONG! If you do not withdraw your money, you get even MORE each year! Why is that, you say? Well, let's say you get $1,050 from that year you got interest. You don't get 5% of $1,000 again, you get 5% of $1,050! You get 5% of the money you gained last year! That means, if it goes on and on, in no time, you'll have a LOT more than $100 going into your bank every year!

Still doesn't make any sense? This line graph shows why you should invest with Hardinge, McComb, Munden & Co instead of leaving perfect money under your bed!

RED shows the money you get if you deposit $1,000 into our company with 5% interest, without withdrawal for 45 years.

GREEN shows how much progress you've made with the money under your bed without withdrawal for 45 years.

The world's BIGGEST prime number

A while back we studied prime numbers. Well, many mathematicians spend tons of time "hunting" for HUGE primes. Here is a video that tells us about how they found the largest (known) prime number..
