Blocks (Whole)
- Count square units to find the area of a shape made from full blocks.
- Read a tiled grid and keep track of units so the answer is in square units.

About these worksheets
Students learn to find the area of shapes using grid-based counting methods. Worksheets progress from counting full blocks to working with partial blocks, then move to using rows and columns for rectangular areas. Activities also include finding area by tiling, continuing area patterns, and calculating the area of right triangles on a grid. These resources align with third through sixth grade standards and help students transition from counting to using area formulas.
Blocks (Partial)
- Find the area of a shape by counting square units on a grid.
- Add up full and partial blocks to get the total area of a figure.
Finding Area
- Find the area of a rectangle by counting square units in a grid.
- Use rows and columns to figure out area without counting every square one by one.
- Write the area using the correct square units (square units).
- Connect area to multiplication by using length × width for rectangles.
Finding Area
- Find the area of a rectangle by multiplying its length and width.
- Use the correct square units (like cm² or m²) when writing an area answer.
Finding Area by Tiling
- Cover a rectangle with equal-size square tiles without gaps or overlaps.
- Count the tiles to find the area in square units.
- Use rows and columns to keep track of tiles and avoid miscounting.
- Explain that area means how much flat space a shape covers.
Finding the Area of Right Triangles with a Grid
- Use the grid to count square units and find the base and height of a right triangle.
- Use the area formula for a right triangle (area = 1/2 × base × height).
- Make sure the base and height you choose are perpendicular sides of the right triangle.
