Hello I just purchased the health and wealth assignment. I didn't realize I needed to have ti 83 calculators for the assignment. I am disappointed that I bought the assignment and wished I selected one where calculators wouldn't be required!!! I would appreciate if you would refund me the money.

21st Century Math Projects (TpT Seller)

Can do. I will put in a request. It can be done with Excel as well. Sorry!

Buyer re: Correlation All-Star -- Integrated Sports Data Analysis & Statistics Project

Hi,

I purchased your project and used Microsoft Excel but the numbers for y and R squared look different than what you have here. Do you have instructions for using this with Excel as well? Or maybe I can send you an Excel sample to see how different it is?

For the students who got married did they need the exact same card, or just both have a card that says they got married? I was looking at the part for the wedding cost and was tryign to figure out how that would work if they didn't get the exact same card. Thanks.

21st Century Math Projects (TpT Seller)

I add the wedding costs together which they then have to pay out of their now joint savings. Welcome to the real world boys and girls!

Annie Davenport (TpT Seller)

I bought your Game of LIfe activity. I was wondering how you did the updates with your students. Are they randomly given the slips, do you control it, or do they get to pick? I am going to use the project with my classes of seniors that are preparing to graduate. I love the idea!

21st Century Math Projects (TpT Seller)

For me it is usually random. Unless of course you need to make a specific special student experience something for comedic effect.

Britney Jackson (TpT Seller)

Hello! I am trying to use the silence the violence with my middle school students and I cant figure out how to set up the proportions for the Homicide and Firearms statistics. How do I set up the proportions?

21st Century Math Projects (TpT Seller)

The Homicide by Firearm per 100,000 people proportion would be (Total number of Homicides by firearm)/(2012 Estimated Population) = (x) / 100,000.

The Average Firearms Per 100 people proportion would be

(Approximate Total of All Civilian Firearms)/(2012 Estimated Population) = (x) / 100

Hope this helps!

I LOVE your CSI products-- my students beg for them…I teach a high 4th grade class (they do 5th grade math). I would love to purchase more-- but a lot of them are a little high…I would love a geometry one that wasn't quite so high…any plans to expand your CSI stuff?

Amanda E. re: CSI: Algebra 1 -- STEM Project -- Complete eBook

The unit 7 solving equations CSI is causing a bit of confusion. the question says that the sum will become 234 but in the answer guide you have the sum written as 37. So when they are solving for p + 2/3p +p/2 we are getting different answers and of course that leads to reasonable doubt for the criminal. Am I reading the scene incorrectly?

21st Century Math Projects (TpT Seller)

That is a typo in the answer key. I can't remember if I changed the question from 37 to 234 at some point in time. I'm correcting it and uploading the file. Sorry!

Carla H. re: CSI: Pre-Algebra -- STEM Project -- Unit 2 -- Factors, Primes & Multiples

I was also confused about Scene #2 the Date Palm Forest, until I read the question at the top of the page pertaining to the same issue. I think if we are questioning it our students will also, especially since it does not mention "unique" in the instructions. Instead, since at the beginning it mentioned 400 bushels of dates, I instructed my students before they started to build a factor tree for 400 instead of 624, then the factors actually do add up to 18. Hope this helps anyone else who is having the same problem.

Other than that, my students and I have loved the CSI projects. This is the 2nd unit I have purchased, and look forward to more. Thank you.

I don't believe I got my question across clearly. The students know how to find an inverse. I guess what I'm asking is what to tell them as far as finding an invertible matrix. Do they just use random numbers? Is it a guess and check situation? I want to steer them in the right direction without actually giving them the answers.

21st Century Math Projects (TpT Seller)

As long as the determinant is not 0, any numbers could work. Larger determinants could lead to more complicated fractions though. In the event you let students use decimals, I would require 3 or 4 significant digits.

Buyer

Regarding my previous email, will I have access to the corrections you made to the Cryptography Code Breaker?

Also, my students are having trouble writing their own encrypted matrices. More specifically the encoding matrix. Any pointers or suggestions?

21st Century Math Projects (TpT Seller)

Yes you can "redownload" the file if you click on "My Purchases" to get that correction. With an Encoding matrix it needs to be a 2x2 matrix that is invertible. You could provide them with a few options from a text book or you could grab some of the invertible ones that I used through the unit. There are some examples on this assignment: http://www.mathworksheets4kids.com/matrices/inverse/10.pdf

I purchase the Cryptography Code Breaker and have a couple of questions. For the "Where in the World is..." clue # 6, I believe you are missing an "e" in Stonehedge. I check and doubled checked your calculations and your answer key. Was this done on purpose?

Also for the scanning portion of it, one of the scanning goes to a music video. It's also confusing as to what the solution is, because you are scanning numbers. Do the numbers translate into the previous code (alphabet)? Or is the solution the music video.

Your help is greatly appreciated.

The solution is the music video. In the intro, I write: “I am about to the find the answer the most important mystery in the universe. #cantcatchthis” The most important mystery should be everyone's favorite "What does the fox say?" I can't believe I made that mistake on Stonehenge, my British citizenship is going to be revoked. I have updated the file. Sorry!

Daria R. re: CSI: Pre-Algebra -- STEM Project -- Unit 2 -- Factors, Primes & Multiples

Hi,

Great projects! Thanks for providing them. I had a question regarding the date palm forest problem in this - the prime factorization of 624. You have it as adding up to 18 - I have the prime digits adding up to 24. Is this a mistake that hasn't been addressed? Or am I missing something?

21st Century Math Projects (TpT Seller)

Peace Daria, I included the word "unique" prime factors to practice that vocab. When it shakes out you should get 2x2x2x2x3x13. The only unique factors are 2, 3 and 13. Totally 18. I left 24 off as an option to avoid that confusion. Hope that helps!

I'm working through the Weapon's Test portion and in the answer key you have the spear clearing the wall and the sling not clearing the wall.

Hello,

I recently purchased (among others) the CSI Alg II (Pre-calc) Polynomial Functions unit. I am embarrassed to say that I have no idea what the image in scene 6 is and how to show/use it with my students. Any chance you can give me a clue so I can give myself a quick tutorial? Thank you very much!

The eagle is just Clipart and doesn't have any impact on the problem if that's the question. Arabic is not a pre-req :-) You just have to use the Cost and Revenue functions to figure out the two problems. Hope this helps!

I recently discovered and purchased several of your Person Puzzles to use in my Algebra 2, Honors Algebra 2, and Honors Geometry courses. I love the way they tie in other subjects and real life people, and look forward to purchasing and trying out many more of your other creative activities. The CSI Projects look great, and the Zombie Apocalypse sounds very entertaining!

However, I'm curious about a possible typo in the Graphing Linear Inequalities puzzle about Benazir Bhutto. Problem #7 (x - y < 2) when solved would flip the inequality sign due to having divided by a negative coefficient (-1) to isolate y (resulting in y > x - 2). Since the line would be a dashed line and shading would be above the line, that means neither point A nor B would be in the solution. Am I missing something?

It could be remedied either by changing the original problem to (x - y > 2) -on both pages- or just switching the number of years on the answer choices so that "A only" is "three years" and "Not A or B" is "nine years".

Thanks,

Jennifer

Tara H.

I recently purchased your Person Puzzles for Surface Area and Volume of Solids and I really like them however I have a couple of problems that I was wondering if you would be willing to investigate.

On the J.K. Rowling (surface area of solids), #5 appears to be missing some information that is needed to calculate the surface area. Using the formula SA = hp + 2B (Virginia Geometry Formula Sheet), there is not enough information to find the perimeter of the triangle and there aren't any notations of right angles, bisectors, congruent segments, etc. I finally solved backwards (using your answer key) and gave my students the correct perimeter to use. Even if you want to find the area of each surface and total them all up, there still isn't enough information to have the dimensions of the faces. On #8 on this same sheet, the correct answer is not given as one of the choices. You have "B" for the correct answer, but that answer does not include the area of the base.

On the Rania Al Abdullah (volume of solids), #7 also does not show the correct answer of 17,280, however "A" is very close. The instructions say round to the nearest tenths, not hundreds.

I appreciate you looking into this for me and look forward to hearing from you soon.

Thanks,

Tara

My kids are loving this math. I actually have my grade 5's doing the CSI Decimal activity with Tenths Dontsaypoint. They have found an error in the key. Tasmanian Devil Translation Challenge the answer in the key should be 351.171 not 350.171.

As well in Scene #3 under Fiji the decimal is missing in front of 78 - to match with the answer and the question it should be .78

I don't know if this will change the rest of the answers or not.

If so, would you be able to do an "update download" option? Thanks so much for this great activity.

What is the harm of a parent sharing not only the answer but the explanation of the answer? It's all teaching. I am sure I don't fully understand the dilemma. I will email you at my next earliest convenience with our specific scene questions. It's Ms. Turkeycat, btw.

Hi We purchased the ebook Algebra 2/ PreCalculus Stem Project ebook and although we have enjoyed that the subject matter has been interestingly presented and the puzzles challenging, we find ourselves a little lost on a few of the assignments. Where can we find more explanation of how the answers were reached? We don't have the textbook you referenced in the description. Is that required? Our Saxon Algebra 2 book and Kahn Academy do not cover some of these concepts to the extent that is needed to understand the solution. Can you direct us to some resources that could help us not only solve, but understand how we got there? Thank you.

Peace Mr./Ms. Turkeycat,

While I would love to include more elaborate solutions, there have been past issues with parents purchasing my items to give their kids the answers :-) I'll gladly guide you through some problems if you want to email me at 21stcenturymathprojects@gmail.com with the Unit and Scene number(s).

I'm so interested in buying this, but wondering if you would be willing to discount further because I have purchased things in the past-- thanks!

Is there a typo in the answer key of the 80% threshold for Oceania? I get a different answer, but get your answer when I do 90%.

MrsGrantMath (TpT Seller) re: Health v. Wealth -- International Data Analysis, Modeling & Correlation Project

My students began this project today in class, and were very engaged! While working on Data Mining with Correlations, we discovered that the 42 Countries for Data Analysis page does not have data for Internet Users and Average Years of School for girls. Am I missing this information? I'm not sure if it is located somewhere else, and I am just not finding it. Thanks!

If you open it on Adobe Reader there shouldn't be a problem. If there is email me at 21stcenturymathprojects@gmail.com and I can try to get you a Google Doc version. Thanks!

Wondering if it would be possible to have a version that doesn't approximate the answers with decimals??? And perhaps a version with a=1 only? Wishful thinking... :)

Hmmm. I can send you the Word Doc if you'd like. Email me at 21stcenturymathprojects@gmail.com if you want it.

Hi! I am interested in your CSI units. I only need the Algebra 1 and Algebra 2/Pre-Calc. Is there a bundle that puts the two together for a discounted price? I see you offer all four for $80, but I won't be teaching those.

Thanks so much!

Betty

Thanks so much!

Thanks for your very quick response. This is the only place that I found to respond to your comment. I still don't see what each letter represents. Is it explained in the problem and I am missing it ?

You can email me at 21stcenturymathprojects@gmail.com if it is more convenient. The letter (in this case C=15) for each of the six scenes are plugged into the "Cryptic Text Message". When all six variables are correctly substituted and calculated, they will simplify to the "favorite number" of the culprit.

TEACHING EXPERIENCE

I am a seventh year teacher in Columbus, Ohio. My experience is primarily working in high-need schools where student engagement and literacy are a great need. To compensate, I have worked to create math projects and activities that are both mathematically rigorous and engaging the students. In my experience I often felt the concepts were lost when I taught other activities that were meant to engage. At the forefront of my work is math rigor that prepares students for standardized tests.

MY TEACHING STYLE

Student engagement by any means necessary. I have taught at an innovative STEM school (where I also served as 9th Grade Curriculum Coordinator) and an International High School (where I serve as Seminar Coordinator), both of which promote cross-curricular collaboration, project-based, inquiry learning.
