Area as Square Units

Area as Square Units

What students learn

Students learn that area is the amount of space inside a shape measured in square units. Start with Area: See Square Units Cover the Inside to see why area counts covering squares instead of edges.

Why it matters

Area helps students understand how much surface a rug, floor, or garden covers. Area: Count the Square Units in Rows shows a grid strategy that keeps the count organized.

Learn the idea

For rectangles, students can count unit squares or multiply length times width. Watch Area: Multiply Length and Width for a Rectangle after the counting example so they can connect the model to the formula.

Try it

Draw a 3-by-4 rectangle on grid paper, count the squares, and then find the same area by multiplying. Ask the student to explain why square units are different from perimeter units.

Parent guide

If the child confuses area and perimeter, bring them back to the picture and ask whether they are measuring the inside or the outside. Let them color the squares so the inside feels visible.
