Lesson objective: Apply understanding of converting measurements in order to compare amounts.

This lesson provides an opportunity for students to apply their knowledge and understanding of measurement conversions to a real-life situation. Students are asked to determine whether students have reached their fundraising goal.

Key Concept students will use:

• when solving measurement problems, it sometimes makes sense to express measurements given in terms of a larger unit in terms of a smaller unit

Skills students will use:

• multiplicative comparisons
• converting from a larger unit, hours, to a smaller unit, minutes
• data from tables

Students engage in Mathematical Practice 1 (make sense of problems and persevere in solving them) as they comprehend and visualize the context and engage in the problem solving process.

Key vocabulary:

• convert/conversions
• equivalent
• hours
• minutes
• range

Special materials needed:

• number line (0-300)
