Plot (Feet and Inches)

Lesson Page 2, Section 1

What you'll work on

Recognize that feet and inches are related units, and understand why you can only add like units while using the conversion factor 1 ft = 12 in to connect the two scales.

Big Idea for this lesson

$A painted illustration of small wooden toy building blocks on a polished oak table — three short red blocks stacked on the left being gently scooped together with seven more red blocks of identical size from the right into a single combined red stack of ten, while a separate stack of yellow blocks of obviously different shape stands untouched beside them. Painterly soft edges, warm honey-amber light, classical toy-maker aesthetic, NO numbers or text or markings of any kind on any block.$

You can only add like units — feet with feet, inches with inches. But you don't have to choose just one: different units can be connected using a conversion factor, so you can see exactly where any measurement lands on both scales at once.
