differentiate between producers and consumers and calculate the cost to produce a simple item

Texas Essential Knowledge and Skills for Mathematics

Teacher's field guide

What Students Need to Do: Students decide whether a person makes or provides something, or buys and uses it. They add the prices of materials needed to make one simple item.
What Mastery Looks Like: Students correctly label people in simple situations as producers or consumers. They add all listed material costs, including repeated items, and state the total with a cent or dollar sign.
Common Misconceptions: Students may think a producer must grow food or work in a factory. They may confuse production cost with the selling price or leave out repeated material costs.
How to Assess It: Give students this exit ticket: “A student uses two 5-cent beads and one 10-cent string to make a bracelet. Find the production cost and name the producer and consumer.”
