Habitat Helpers

The fourth graders got to be habitat helpers as they helped the Audubon and the city of Portland by planting native species back into our community in Baxter Woods. The fourth graders got to learn about the importance of the Chestnut Tree and the work that is being done by the city to bring this tree back to Portland. They also worked to improve the meadow area by planting native wildflowers that attract insects and native birds back to the area. While learning and volunteering the fourth graders also had a little bit of fun. For more photos check out the Snapshots Page!

We can create our own sequence inspired by Fibonacci.

Can you identify the pattern? What number comes next?

The fourth graders took what they learned from studying, analyzing, extending, and drawing Fibonacci's spiral and sequence and created their own pattern with a matching visual. The fourth graders worked on their own or with a group to create a sequence of numbers that had a repeating pattern. They tried to make their pattern complicated enough that it would require thought to figure out. They then had to create a visual representation that matched their pattern. This project not only required them to use different math skills, it also pushed their creativity and teamwork.

Once the posters were finished we hosted a Pattern Carnival in which groups got to explore other patterns in the classrooms. The mathematicians engaged with each other as they asked questions of each other and tried to figure out other groups patterns.

Exploring the Fibonacci sequence

What do you notice about those numbers?

What patterns do you see?

What is the next number in the pattern?

What is the 21st number in the pattern?

The fourth graders worked on answering these questions and more as they explored the Fibonacci Sequence. The Fibonacci Sequence is a pattern of numbers that was found and is observed in math and also in nature. This work encouraged students to identify patterns and think flexibly as they worked to expand the sequence and find ways to represent this pattern visually. The students worked on their own or in small groups to expand the pattern and record their thinking visually. Afterwards they had the opportunity to share in groups and then whole class. The mathematicians asked and answered great questions as they explored how other classmates worked through this same problem. Ask your fourth grader about their exploration of the Fibonacci Sequence.
