Teaching Math​ in the Garden
Math in the Garden
Picture
There are so many ways to teach math in the garden!  Just look at all the opportunities on the back of a seed packet. Teachers at every grade level can find a way to discuss math while planning, planting, observing, and harvest a garden.  At the same time, you'll be showing your students how math is used in everyday life.  Check out these ways to dress up your math lessons with a little green.

Seed Statistics

Not every seed you plant will germinate (sprout), but how many of them do? Students plant seeds and record how many they planted. Younger students write number sentences showing germinated seeds compared to duds, and older students show the difference with fractions and decimals.

Making A Garden Map

Picture
What’s the first step to planting a vegetable garden? Make a plan!

Seeds and seedlings can’t be plopped just anywhere in the garden. Different plants require different amounts of space to grow. And plants grow to different heights, so you need make sure that tall plants don’t shade the smaller plants.

Before you go out to the garden, teach your students how to determine what space requirements their plants need. Then have them draw a map of their garden on graph paper. This activity gives your students a chance to use their math skills in a real-life setting. It also gives them ownership of the garden from the start.

Comparing
 Soil and Air Temperature

Picture
Do your students know that the temperature of the soil and the temperature of the air are not the same? Farmers and gardeners need to pay attention to soil temperature to know when to plant the first crops in the spring.  Soil holds heat better than air and is usually warmer than the air.  In this lesson, students learn the relationship between soil and air temperature, using their math skills to compare and graph the changes in both temperatures during a planting season.

Grades 4-5 (can be modified for grades 2-3 as a whole class observation)

Vegetables
​ Take Over the World
Picture
In this fun math lesson, students use their addition and multiplication skills to answer the question “could vegetables take over the world?” Students count the many seeds in sweet peppers, or other vegetables with many seeds. Then they must determine the number of plants that would grow from future seeds in each of the next five years.

Grades 2-5 (Can be modified for many grade levels.)

The Christmas Farm

Picture
In Mary Lyn Ray's delightful book Christmas Farm, Wilma and her young helper Parker order 62 dozen evergreen seedlings to start a Christmas tree farm. Year after year, the pair nurture their trees, keeping careful count of how many perish and how many grow into fine, full Christmas trees.

The book is full of math problems for fourth and fifth graders and has the added benefit of teaching students the process involved in growing Christmas trees.
