Solve It! Friday- Task #10

Here's how Solve It! Friday works:
1. Each Friday morning (at 12:00 AM Central Time), I will post one problem-solving task. Note: In some cases, I may post more than one version of the task to reach a wider variety of grades. 
2. Before the next Friday, use the task with your students. 
3. Have students solve the problems individually or with a group. 
4. Individual students or student groups create posters using numbers, pictures, and words to illustrate the solutions. Note: The blank backs of old book covers make great poster paper! 
5. Either via a math talk session or a gallery walk, be sure to have students share their responses with other students. 

I would love to see your students' responses and showcase them on social media. Please post your students' responses to Twitter using the hashtag #RMTSolveIt(week number). For privacy, please be sure that students' names and other identifying information is located on the back of the poster. Be sure to check out other classes' solutions using the same hashtag to filter the Twitter results. 

I look forward to seeing your students' work! Thanks for sharing! 

Extension: For students who need an additional challenge, add the following piece of information before asking the question, "Grandma Pat used 11 total bags." (Note: Adding an additional constraint restricts the solution to just one possible solution instead of two. You may choose to present this condition before or after posing the initial question.)

Solution: The real beauty of this task is in the process. Please emphasize that with your students. It may take some time to solve this problem. Validate their efforts and ask questions to move them in a different direction if needed. For your convenience, I have provided the solution below:

#RMTSolveItWeek10: There are two possible solutions. Grandma Pat could have baked 10 cinnamon spice muffins and 27 blueberry muffins or 25 cinnamon spice muffins and 12 blueberry muffins. The answer to the extension is 10 cinnamon spice muffins and 27 blueberry muffins.
