*Multiplication practice from a nature art approach. Use pine cones to make math fun.*

At 1:00 pm, a young student stares out the window, oblivious to the math lesson: at 4:00 pm, that same student stares at a pine cone she found on the walk home. Her eyes follow every crevice, and as her fingers trace the rough sticky surface, as she breaths it's fresh aroma.

Engage your little naturalist and help her develop multiplication skills, algebraic skills, and over all number sense with this colorful project. (It makes a great Christmas ornament too!)

### How to practice multiplication with pine cones

Tell your students to choose their base number, and paint that number of bristles. Here, I started with two.

Next, tell them to take their base number times their multiplier to get your second number of (n2).

Here 2x2=4, so I painted four bristles.

Now, tell them to multiply by the second number (n2) by the multiplier again to get the third number (n3). In this case, 2x 4= 8. If you're working with a large group, it might be easiest to have them go back to the original color as I did here.

Continue multiplying each result by the multiplier, and painting the new number of bristles until they reach the end of the cone.

More pine cone math fun

Here I started with a base number (n0) of 3, multiplied by three each time. (f= 3n). I chose a new color each time.

On this one, I began with three and multiplied by two . f=2n and n0=3.

You can really see the effect of the starting number and the chosen multiplier. As your students work, they will have the chance to notice the pattern of the pine cone. Your little naturalist may find herself enthralled with math yet.
