Grade 4 Unit 2 Addition and Subtraction
Unit 2 - Addition and Subtraction
Content Emphasis/ Big Ideas
Students extend their knowledge of place value to numbers in the millions. Students increase their estimation skills and develop understandings of equality and the properties of addition.
Students apply these understandings and skills to increase their computational fluency and accuracy with addition and subtraction and to solve various types of multistep practical problems involving addition and subtraction. Students also explore numerical patterns.
