Students use these terms and representations in reasoning about situations that involve constant speed, unit pricing, and measurement conversions. Then, special focus is given to circumference and area of circles as examples of proportional and nonproportional relationships, respectively. Students informally derive the formulas for circumference and area of a circle and are introduced to the value \(\pi\).Read More
