7+7

Mrs. Young

4/8/2020 09:22:01 am

Awesome, Amir! What makes 7 + 7 different than the other three?

Greta

4/6/2020 09:28:59 am

8+6=14... 7+7=14... 5+9=14... but 8+7=15 so 8+7+15 does not belong.

Mrs. Young

4/8/2020 09:22:39 am

I agree, Greta! And you did a fabulous job clearly explaining your reasoning.

Max

8 + 7 because the others all add up to 14

Collin

8+7

Grace B

7+7=14 8+6=14 9+5=14 so the answer is 8+7=15

Mrs. Z

8+7 does not belong because it equals 15.

Anjali

4/6/2020 12:20:11 pm

8+7 doesnt belong because because it equals 15 and the other equal 14

Mrs. Young

4/8/2020 09:25:27 am

I agree, Anjali! :)

Mrs. Young

4/8/2020 09:24:48 am

Zander Lippolis

4/6/2020 10:29:06 am

8+7 because all the other ones are 14.

Mrs. Young

I agree, Charlotte. What makes 8 + 7 different than the others?

charlotte gallegos

4/6/2020 10:35:24 am

8+7 because the rest equal 14 and that one equals 15

Mrs. Z

4/8/2020 11:02:37 am

Ellie Fuller

4/6/2020 11:52:32 am

8+7 does not belong it equals 15. the other ones equal 14.

I agree, Ellie. And I love how you clearly explaining your reasoning.

Great thinking Ella! I agree with you!

Tyris

4/6/2020 12:17:14 pm

8+7=15 it does not belong because other numbers were equaled to 14.

Mrs. Young

4/8/2020 09:29:06 am

Nice job, Tyris. It's easy for me to agree because you clearly explained your reasoning.

Ronan Conz

8+7 is different. all the others equal 14, but 8+7 = 15

Mrs. Young

4/8/2020 09:30:57 am

Great job, Lila. I agree and your reasoning is so nice and clear.

isabel

4/6/2020 01:46:27 pm

8+7 is different then the others because the others equal 14. 8+7=15.

Mrs. Young

4/11/2020 07:24:20 pm

I agree, Isabel. Great job!

isabella Cataloni

4/6/2020 01:53:02 pm

8 + 7=15 doesn't belong because it doesn't equal 14 like the rest.

Mrs. Young

4/8/2020 09:35:48 am

Way to go, Izzy. You stated your answer and your reasoning clearly. I agree with you. :)

Harrison MacKay

4/6/2020 02:00:54 pm

There is one that equals 15 but the rest equal 14. 8+7=15

Mrs. Young

4/8/2020 09:31:40 am

You got it, Harrison. I can understand your reasoning quite clearly. Well done!

Erin Calio

4/6/2020 02:17:48 pm

8+7 is different because it equals 15. All the others equal 14.

Mrs. Powers

4/9/2020 12:09:31 pm

Hi Erin! I agree - and you did a great job with your explanation.

Will Toczylowski

Will Toczylowski

8+7 doesn’t belong because it equals 15

Mrs. Z

Great thinking Will! I agree with you!

Jackson Rolince

4/6/2020 04:44:04 pm

Mrs. Z

4/8/2020 11:05:23 am

Hi Jackson! I love your thinking and I agree with you!

Will Gallagher

4/6/2020 05:11:02 pm

8+7=15. 5+9=14. 8+6=14.7+7=14

Will Gallagher

4/6/2020 05:15:29 pm

8+7 does not belong because it equals 15.

Mrs. Young

4/8/2020 09:32:57 am

Will, I'm so proud of you for explaining your thinking, but then going back to revise your response. By adding your second response, you answered the question clearly. Nice job!

Heidi

4/6/2020 07:33:25 pm

The 8+7=15 does not belong there because the rest equals 17.

Mrs. Young

4/8/2020 09:34:39 am

Heidi, your strategy for explaining your reasoning is spot on. I think you may have a typo though. Did you mean 17? I have a feeling your finger may have hit another button nearby on the number pad ;-)

Kierra P

4/7/2020 08:29:42 am

8+7=15

Mrs. Z

4/8/2020 11:05:57 am

Awesome Kierra! I agree with you!

Mrs. Powers

4/7/2020 02:14:38 pm

WOW!!!! Look at all these responses second grade mathematicians! So proud of you - keep up the great thinking.
We all miss you!

Avery

4/7/2020 03:21:14 pm

8+7 does not belong

Mrs. Powers

4/13/2020 08:54:39 am

Can you tell me why Avery? I'd love to hear some more math reasoning in your reply!

Ryan O’Neil

4/8/2020 11:23:12 am

8+7=15 and it doesn't =14

Mrs. Young

4/11/2020 07:25:13 pm

You're right Ryan. That makes it different from the others. Way to go!

Kim Fauria (Hadley)

4/8/2020 11:25:38 am

The box that doesn't belong is 8+7 because that = 15 and all the other boxes = 14.

Mrs. Powers

4/9/2020 12:11:06 pm

Hi Hadley! Great job with your explanation. Miss you!

Charlotte

4/9/2020 01:09:05 pm

8+7 does not belong because the sum is 15. The sum of the other equations is 14.

Mrs. Powers

4/13/2020 08:55:42 am

Excellent explanation Charlotte!

7+7 doesn't belong because it is the only dobble

Isabel Norman

4/23/2020 02:23:16 pm

I think 7+7 dose not belong. because it is the only one that has the same number twice. but all of them have the same amount.

Where's the Math!?
