Everything is looking pretty festive around our house. My husband and son helped me put up outdoor twinkling lights over the Thanksgiving holiday, and last Friday Barney, Danny and Gina were visiting and helped me decorate our holiday tree.

"Where did you get so many cute decorations?" asked Gina. 
 

"Oh, I get them as presents from my students," I said smiling as I hung one that said "World’s Greatest Teacher."

"You must have enough to decorate two trees!" said Danny, holding his favorite, a gingerbread house decoration. "Say, this reminds me -- when are we going to make cookies?" (Danny is always thinking about food.)
 

 

Baking Cookies

"Not until I get all these presents wrapped," I sighed. "I have to take them to the fire station for our annual Toys For Tots collection."

"Aunt Mathilda, your talents are going to waste!" wailed Danny. "Hey, I have an idea. What if you bake cookies and we wrap the presents?"
 

"Great idea, Danny," agreed Barney. "I know we could get this whole pile wrapped by the time Aunt Mathilda makes a batch of cookies!"

"That sounds like a plan!" I smiled and quickly gathered the wrapping paper, tape and ribbons for the children to use.

When I returned from the kitchen after taking a batch of Snickerdoodles out of the oven, the children had already completed the task.
 

"How did you do that so quickly?" I asked. "It takes me forever to wrap one tiny package and they never look this lovely!"

"We each wrapped our own packages, but we helped hold things for each other," explained Gina, beaming with pride.

"And we had time to figure out a math challenge for you too!" added Barney.

"We’ll tell you while we sample those cookies!" added Danny, heading for the kitchen.

While eating the cookies, Danny explained the challenge.

"We wrapped 11 presents altogether," he said between bites.

"If you added the presents Danny and I wrapped, it would be 6," explained Gina. "But if you added the presents Barney and I wrapped, it would be 7."

"Your challenge, Aunt Mathilda, is to figure out how many presents we each wrapped," Barney said.
 

"I guess you wouldn’t be satisfied with the answer 'a lot!,' would you?" I said laughing. "Well, I’d better have another cookie while I think about this one!" I said, reaching for the plate.

Can you get this challenge "wrapped up?" How many presents do you think each child wrapped?
 

After you think about this awhile and work out the answer, be sure to show an adult your solution and talk with them about it. They may be surprised at how you thought about it. They might have thought about it a different way that might surprise you too. It's always interesting to see how different people think about math problems. Remember, the best way is the way that makes sense to you!

Love, Aunt Mathilda


I'd like to try the wee bit easier challenge, please.

I'd like to try the wee bit harder challenge, please.

I'm a parent/teacher and want to review parent/teacher tips for this challenge!
