The roadrunner bird can run 14 times miles per hour. That's 7 times faster than an ostrich can walk. How fast does an ostrich walk?
7 X ?= 14 I would write the equation like this. Not sure my 8 year old would be able to do this.
She knows that 7x 2 or 7+7+14, but they want you to show your work. Not sure how best to do that.
My daughter is working on a Common Core Math multiplication problem. How does she show her work? They haven't started division yet. This seems like a division problem.
Thank you!!
I've sent this to my daughter-in-law who teaches and specializes in common core math in the lower grades. I hope she sees it in the next few hours. Please check back later.
Thank you. I'll check back.

To find the speed at which an ostrich walks, let's solve the equation 7x = 14, where x represents the walking speed of an ostrich.
To show the work, your daughter can use a method called repeated addition. Since she knows that 7 x 2 = 14, she can write it out as:
7 + 7 = 14
This demonstrates that if the walking speed of an ostrich is doubled (or multiplied by 2), it will reach a speed of 14 miles per hour. Therefore, the walking speed of an ostrich is 2 miles per hour.
By using repeated addition, your daughter can show her work on the paper. Keep in mind that this method aligns with the concept of multiplication, even though it may resemble addition more closely.
Hope this explanation helps! Let me know if you have any further questions.
