__Mathematical Mindsets__) states, "Can you find every number between 1 and 20 using only four 4's and any operation?" In the meantime, I was also working on this activity.

A few hours later, my son called. They were done! How could that be? I was still struggling with some of the numbers. My son shared that he taught my older grandson about square roots and factorials, and that helped them to complete the challenge. I hadn't thought about square roots and I had forgotten what factorials were. (Goes to show how much math I've forgotten!) When I asked my son to send me their work so I could check the ones I was missing, my son refused. "Not until you're done," he told me. Well, for the next week, the problem consumed me! I found myself thinking of possibilities while I was driving and rushing home, only to find out I already had that number. I finally Googled it so I could say I was done :-)

I enjoyed teaching math even if it was just to elementary aged students. I found it challenging but so rewarding when students "got" what I was trying to teach. When I went to a workshop about using a problem-solving model that encouraged students to collaborate and share strategies, it was an "aha: moment for me. The kids liked it, too, much better than drill and kill worksheets. After reading

__Mathematical Mindsets__, though, I realized that we hadn't gone far enough. Instead of a problem-solving model, we need to teach with a project-based model where students have opportunities to solve open-ended problems like "Four Fours." As a school, we're learning more about project-based learning, and it's important that we find ways to integrate or embed real-world mathematics into our projects.

Today, our second graders held another Garden Sale. They have been practicing lots of math skills as they plant, grow, harvest, and sell their veggies. As they reflect and expand on this project, I see so much potential for them to learn and apply math throughout this project!

Next year, one of our school's focuses will be on improving the teaching and learning of mathematics. We need to emphasize a mathematical mindset that values persevering through struggles and learning from our failures. It won't be easy, but I look forward to the challenge!

Our second graders are so excited about their garden! Today, they harvested cleaned, packaged, and sold carrots, kale, mustard cabbage, and choy sum. |

Students took orders from customers and figured out how much they owed. Different students will have the opportunity to apply their math skills to real-life situations. |

These students collected the money and gave customers change. Students are learning new skills and getting better with making change. |
