Heidi Selken, November 2016
Discussion Question: Heidi told us about the technology that they use on their farm with the Electronic ID tags. This allows the farmers to keep a closer eye on the cows and take better care of them. What are some ways that technology has made your life easier?
Core Standard & Question: 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, distinguishing multiplicative comparison from additive comparison.
Each cow on the farm gives about 10 gallons of milk each day. How much milk is produced by all 2,000 cows on the farm in one day? One week?
Teacher Resource: If you would like to discuss what happens to the milk after the cows are milked, here is a great (short) video that explains the process!
