Illustrative Mathematics Units of Study 

The big ideas in grade 4 include: developing understanding and fluency with multi-digit multiplication, and developing understanding of dividing to find quotients involving multi-digit dividends; developing an understanding of fraction equivalence, addition and subtraction of fractions with like denominators, and multiplication of fractions by whole numbers; understanding that geometric figures can be analyzed and classified based on their properties, such as having parallel sides, perpendicular sides, particular angle measures, and symmetry.

The mathematical work for grade 4 is partitioned into 9 units:

📏 Unit 1: Place Value, Rounding & Algorithms for Addition/Subtraction

Students explore large numbers, understand place value up to one million, and learn efficient strategies for adding and subtracting multi-digit numbers.

✖️➗ Unit 2: Multiplication & Division (Part 1)

Students build on multiplication and division strategies using area models, number lines, and arrays—laying the foundation for fluency with larger numbers.

📐 Unit 3: Measurement

Students measure lengths, weights, volumes, and time, and solve problems involving conversions (e.g., feet to inches or minutes to seconds).

🔲 Unit 4: Area & Perimeter

Students learn how to calculate area and perimeter of rectangles and other shapes, using real-life examples to make it meaningful.

✖️➗ Unit 5: Multiplication & Division (Part 2)

This unit focuses on two-digit by one-digit multiplication and long division with remainders, helping students make sense of more complex problems.

🟰 Unit 6: Fractions (Part 1)

Students learn about equivalent fractions, comparing fractions, and placing them on a number line—all key for developing fraction sense.

➕ Unit 7: Fractions (Part 2)

Students add and subtract fractions with like denominators and begin working with mixed numbers.

📊 Unit 8: Geometry & Measurement (Angles)

Students explore lines, angles, and shapes, and learn how to measure and draw angles using protractors.
