This Grade 3 mathematics worksheet helps students find the area of shapes by counting square units and multiplying the number of rows by the number of columns. Students answer 14 multiple-choice questions and one open-ended question using visual area models, shaded shapes, rectangles, square tiles, and real-world contexts such as gardens, floors, rugs, and box lids. The questions also reinforce that area measures the space inside a shape and require students to identify appropriate square units, including square inches, square feet, square centimeters, and square units. The worksheet is designed for guided practice, independent work, or a quick assessment of students’ understanding of rectangular area. It gives learners repeated opportunities to connect unit-square models with multiplication, interpret dimensions, select the correct area from plausible choices, and explain an area answer in an open-ended item. This is a free printable worksheet with a complete answer key for convenient checking and review.

This Grade 3 worksheet focuses on finding area by counting unit squares and multiplying the number of rows by the number of columns. Its 14 multiple-choice items and one open-ended item use area models, shaded shapes, rectangles, square tiles, and real-world situations, helping students connect visual units with measurements such as square inches, square feet, and square centimeters.
Begin by modeling how a rectangle can be covered with unit squares, then show that counting rows and columns leads to multiplication rather than addition of the dimensions. Use the worksheet’s visual models and shaded-shape questions for guided practice before assigning the garden, floor, rug, and tile contexts independently. Ask students to explain both what the square units represent and how their multiplication matches the model.
Watch for students who confuse area with the distance around a shape, add the number of rows and columns, or choose a numerical answer without the required square-unit label. In the rectangle and tile-model items, students may count only one row or column instead of the total unit squares. For the word problems, check that they multiply the given length and width and report the result in the stated units, such as square feet or square centimeters.
You can assign this worksheet as a printable PDF or as a digital quiz on Wayground, and it includes a complete answer key for checking the multiple-choice and open-ended responses. Printable submissions can also be graded by scanning student work with the Wayground for Teachers app.
Use the worksheet’s Advanced Settings to create an alternate version with wider font spacing or a larger font size so students can work more comfortably through the area models and word problems. You can also apply a dyslexia-friendly font or translate the worksheet’s instructions and contexts into another language.
