Understanding Area
Understand that a unit square has one square unit of area and that the area of a plane figure is the number of unit squares that cover it without gaps or overlaps

Set out your lesson
“Area measures the two-dimensional space inside a boundary in square units. For a rectangle, equal rows and columns connect area to multiplication.”

- Step 1. Use grid lines to draw a 3-by-4 rectangle and a 2-by-5 rectangle.
- Step 2. Count complete unit squares by rows and columns.
- Step 3. Write length × width for each rectangle.
- Step 4. Compare areas and explain why square units are used.
- Quick check. Draw a 5-by-3 rectangle. Success means your child finds 15 square units and distinguishes area from perimeter.
Worked example. A rectangle 4 squares long and 3 squares wide has 3 rows of 4, so its area is 4 × 3 = 12 square units.
Optional challenge. Draw two different rectangles with area 24 square units and compare their perimeters.
What to notice. Save a photo of one labeled rectangle with its square-unit count and multiplication equation, or a short parent note recording the explanation.

Check understanding
- Identify a unit square and state its area is 1 square unit
- Explain why a figure covered by 12 unit squares has area 12 square units
- Distinguish between area and perimeter as different measurements
“If your child counts the small squares inside a rectangle drawn on squared paper, can they tell you the area — and explain what "one square unit" means?”
