Fourth grade to implement comprehensive new Illustrative Mathematics Program this year!
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:
Factors and Multiples
Fraction Equivalence and Comparison
Fraction Operations to Fractions
From Hundredths to Hundred-thousands
Multiplicative Comparison and Measurement
Multiplying and Dividing Multi-digit Numbers
Angles and Angle Measurement
Properties of Two-Dimensional Shapes
Putting it All Together
