**Clint Brandlee Adopt-A-Farmer Video 6 Questions:**

- **Core content standard questions**:

**Story:**Farmer Clint is preparing his field for planting. He applies a solution of 12 gallons of water + 20 ounces of Roundup chemical per acre on the field.**Provided:**1 gallon = 128 ounces

**- Conversion **(gallons to ounces) **4.OA.2**

Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem), and distinguish multiplicative comparison from additive comparison.

**Question**:*How many ounces are equal to 12 gallons?*- Work: 128 (ounces per gallon) x 12 (gallons) = 1,536 (ounces in 12 gallons)
- Answer:There are 1536 ounces in 12 gallons.

**- Fractions **(comparing ) **4.NF.2**

Compare two fractions with different numerators and different denominators, by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols <, >, =, and justify the conclusions.

**Question:***What is the correct comparison using fractions for the amount of Roundup to water in Farmer Clint’s solution?*- Work: 20 ounces of Roundup + 1,536 ounces of water = 1,556oz in total solution
- Solution: 20/1,556
**<**1,536/1,556

- **Discussion question**:

*Clint talked about new technologies on the farm. What were some of the ways that he used technology during planting?*
