Area Model Multiplication Worksheet

This 4th grade sheet has 9 area model problems. In Part A students multiply a 2-digit number by a 1-digit number in two boxes, and in Part B a 2-digit by 2-digit product in four boxes, with the place value parts already written. In Part C students split both numbers themselves. No number has a zero digit, so every box holds a partial product.

Tips for teachers and parents

  • Start with the parts: 89 is 80 and 9, so the rectangle is split into an 80 column and a 9 column. The side works the same way.
  • Each box is one multiplication of two parts. Use multiplying multiples of 10 for the big box: 40 × 30 = 1,200.
  • Add the boxes at the end. Adding the largest box first and the ones box last keeps the place values straight.
  • Compare with the standard algorithm: the boxes hold the same numbers as the rows of the written method, just drawn as a picture.

Common mistakes

  • Splitting 75 into 7 and 5 instead of 70 and 5. Ask: what is the 7 really worth?
  • Multiplying across a row and down a column but leaving one box empty. An area model for two 2-digit numbers always has four boxes to add.

What to practice next

Once the boxes feel easy, try the same problems with the standard method on the 2-digit by 2-digit multiplication worksheet.

Frequently asked questions

What is area model multiplication?

A way to multiply by drawing a rectangle split by place value. Each box holds a partial product, and the sum of the boxes is the answer.

Is the box method the same as partial products?

Yes. Both find the same four products and add them; the area model shows them as parts of a rectangle.

Is there an answer key?

Yes, page 2 of the PDF shows every box, the split numbers in Part C, and the total for all 9 problems.
