Learning About Educreations and Problem Solving!

In class, we have been learning how to use logical reasoning to figure out math problems. Here are the steps for solving a logical reasoning hundreds chart problem:

First, read the entire math problem. Second, underline important clues. (Some clues were very useful, while other clues didn't help very much.) Third, use the clues to identify numbers that are in or out. Next, circle numbers that match the clues, and cross out numbers that do not match the clues. When you reach your answer, REREAD the clues to make sure your answers is correct!

We are also learning how to share our thinking using Educreations. 

Here are a few Educreations modeling the logical reasoning process. These are our first Educreations, and we would like to get better at them! 

Kate, Asha, and Derrick made their first Educreation.

 Nick. Sydney, Ethan, and Ruby made an Educreation:

Troy, Winston, and Leah made an Educreation:

Mrs. Yollis even made an Educreation! Here is her presentation about clues that involve the SUM of the DIGITS. 

 Here is an Educreations demonstrating the answers to Mrs. Ranney's challenge!

 What are some math patterns that you like? 

 What are some tips you can offer for making a great Educreation? 

Check back later this week for more Educreation additions! 


  1. Dear Mrs. Yollis,
    I am having so much fun with standard form,expanded form, and writing form.

  2. Dear Mrs. Yollis and Third Graders,

    I love hearing all of you explain logical reasoning on your Educreations. That makes doing math problems so much easier!
    I wish you were around when I was in third grade.

    Keep up the good work!

  3. Good morning Mrs. Yollis and Class,

    I just got back last night from a trip to New York where I visited my daughter and her husband. When I checked your blog this morning, I was delighted to see your wonderful Educreations! I am particularly impressed with how well all of you expressed yourselves and spoke so clearly!

    Here are a couple of problems for you to solve using the hundreds chart. Maybe you have already come across these problems in class!

    1. I am a number in the fourth row of the hundreds chart. Both of my digits are odd. My ones digit is four more than my tens digit. What number am I?

    2. I am an even number in the last row of the hundreds chart, but the sum of my digits is odd. What numbers can I be?

    I'm looking forward to seeing who can use the clues to come up with the answers! Keep up the great work, everyone!

    All the best,
    Mrs. Ranney

      @ Mrs. Ranney,

      Thank you for the outstanding number problems! We really liked solving them.

      We are now making Educreations using your creative comment.

      What were some of the activities you did in New York? Did you go to Manhattan? What was the weather like in the city?

      Mrs. Yollis told us that you will be coming to our class to work with us every now and then. We can't wait to see you!

  4. Hello Mrs Yollis and class,

    I really enjoyed hearing you use logical reasoning to solve the problems. Great job!

    I think Educreations is a super app for explaining your thinking. How do you think it helped your learning?

    I wonder if you can use logic to work out the following problem.
    I am a three digit number less than 180.
    All of my digits are odd.
    The sum of my digits is seven.
    The digit in my hundreds and ones place is the same.
    What am I?

    Keep up the great work!

    From Miss Crowther :)

  5. @Nic, Asha, Leah, Derrick, and Kiano,

    What a wonderful job you did solving and sharing about the second challenge problem! I look forward to seeing who can solve the first one as well!

    While in New York, I spent most of my time in the burrough of Brooklyn because that is where my daughter and her husband live. I also spent a day in Queens and some time in Manhattan. The weather was very pleasant most of the time. However, it did rain one day and was often quite humid!

    Two activities I really enjoyed were visiting Coney Island and taking a walk across the Brooklyn Bridge! I have published posts about both places, so you can see some photos! Here are the links:

    I'd love it if you'd check out the posts and leave a comment! There is also a post about the Tall Ships Festival that I had written to you about a while back!

    Keep up the great work on solving math problems and sharing with Educreations!

    Hope to see you all soon!

    Mrs. Ranney

  6. Dear Mrs. Yollis,

    I was thinking that on Friday, Saturday and Sunday the homework could be doing creative art work or music. (optional)

  7. Dear Mrs. Yollis and class,

    First, let me thank you for sharing all your challenging math problems. Each math problem is like a fun puzzle, and I really enjoy the process of finding the answer. The hundreds chart sure does help as has your Educreations!

    Next, I have really enjoyed re-learning about numbers in their standard, expanded and word form. I often need to write numbers out in word form (for example when I write out a check to pay a bill) so it has been quite helpful to review these math problems along with your class! I wonder if anyone else has found ways in which this has helped them in their everyday life?

    Finally, and on a different topic, I really enjoyed Mrs. Ranney's photos of the Brooklyn Bridge. It seems as though she had a most enjoyable trip! I too love to travel and would appreciate hearing about some of the places you all have visited over the summer or hope to visit in the future.

    I hope you all have a wonderful week!

  8. Dear Tabby,

    I like your creative comment.
    I might be creative and do what you said. I love to create art and I love to sing. We have free time so its a really good idea.


  9. Dear Asha,

    Thank you for commenting to me. I also love to create art and sing. Mrs. Yollis agrees that it is a good idea. Will you do it at least once?



  10. Mrs. Yollis and class:

    I am so impressed by your learning! I hope you don't mind, but I want to show your work at a conference of teachers, here in Western NY State. They will be so impressed...many are just learning to become teachers...and you are ALL excellent teachers already!

    Thanks for sharing your work!!
