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.
Standards:
- 4.NS.1 The student will use place value understanding to read, write, and identify the place and value of each digit in a nine-digit whole number.
- 4.NS.2 The student will demonstrate an understanding of the base 10 system to compare and order whole numbers up to seven digits.
- 4.CE.1 The student will estimate, represent, solve, and justify solutions to single-step and multistep problems, including those in context, using addition and subtraction with whole numbers.
- 4.PFA.1 The student will identify, describe, extend, and create increasing and decreasing patterns (limited to addition, subtraction, and multiplication of whole numbers), including those in context, using various representations.
