### Planning a Garden

*shape*and

*dimensions*of the garden. For example, this picture shows a 15’x12’ rectangular garden layout.

*rows*or

*columns*, depending on the shape and dimensions of the garden. The example garden has been broken up into 4 planting rows, 4 walking rows (brown), a bed of carrots, a column of tomatoes, and a column of pumpkins.

**Planting Rows**:

**Bed of Carrots**:

**Column of Tomatoes and Column of Pumpkins (equal size):**

Area

*area*of the garden is essential, especially when buying fertilizer. Fertilizer can be expensive, so it is important to only buy as many bags as necessary. Each bag of fertilizer tells the

*surface area*it will cover, so the easiest way to ensure you will have enough fertilizer without over buying is to use the mathematical

*equation*: Area of garden/Area of 1 bag fertilizer = # of fertilizer bags needed.

(Geometry, Measurement)

Perimeter

*perimeter*of the garden in order to know how many feet of fence is needed. Perimeter is calculated by adding up the measurement of each side. Our sample garden would need 54’ of fence to go all the way around. 12’+15’+12’+15’= 54’

### Planting

*distance measurement)*, the likelihood the seeds will germinate

*(probability)*, how long they will take to reach full maturity, as well as the cost per packet!

### Harvesting

Once your plants start producing vegetables, you can measure and record your daily yields.

For cucumbers you could measure and record the length of the fruit, as well as weight.

For example:

- Count how many cucumbers you harvest each day and make a chart to record your results.
- For green beans you could weigh your harvest each day you pick and record it on a chart.
- At the end of the season, make a graph to find out when the peak yield was, what was the average yield, and how much you harvested total.

### Now What? Using the Harvest

You can practice fractions when you cut up your tomatoes and pumpkins to cook them. Each individual fruit or vegetable is its own whole. Practice finding halves, quarters, and any other fractional piece you can safely cut. Name what shapes the fruits and fractional pieces are.

Cooking and preserving are good ways to practice conversions. When making a batch of mashed potatoes determine how many pounds of potatoes you will need to feed the whole class.

Ratios and measurement conversions are important when making pickles.

For example, when making dill beans it is important determine how many pounds of green beans you will need to make 7 quarts of dill beans.
