Solve It! Friday- Task #4

**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!

**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:

**#RMTSolveItWeek4: **The question specifically asks for the amount raised by fourth grade. However, I will provide all of the amounts for your reference: Third Grade- $700, **Fourth Grade- $500**, Fifth Grade- $400

The clues in the problem don't match the answer. If 4th grade raised $400 and the clue says 3rd grade raised $200 more than 4th, wouldn't that amount then be $600? My students enjoyed the process of solving and understood the need to be precise in their calculations, but they had difficulty reaching a total of $1600 with the clues as they are presented.

ReplyDeleteThank you so much for letting me know! I tried to modify this problem from another version that I saw and got the clues jumbled up. It's fixed now! I'm so excited that you tried the problem with your students. What a great opportunity to emphasize supporting their answers with information from the problem to prove that their work was indeed correct and reveal an error in the problem itself. Awesome teachable moment!
