Big Ideas: Any number, measure, numerical expression, algebraic expression, or equation can be represented in an infinite number of ways that have the same value. Measurements given in large units can be written as an equivalent amount in a smaller unit by using multiplication. In this lesson, students will need to apply their knowledge of standard mass unit conversions in order to solve a math task involving comparing weights and prices of cookie ingredients. Students will need to determine what the optimal combination of ingredients will be in order to get the best deal. Vocabulary: pound (lb), ounce (oz) Special Materials: none
