Operations & Algebraic Thinking Grade 1 Worksheets

Operations and Algebraic Thinking is a key domain in the Grade 1 Math Common Core Standards. It involves understanding and applying properties of operations and the relationship between addition and subtraction. Worksheets are an effective tool to help students practice these skills.

Basics of Addition Worksheets

Addition worksheets for Grade 1 students start with adding small numbers. They include exercises like combining two or more numbers to find their total or sum, using objects, drawings, and equations.

Basics of Subtraction Worksheets

Subtraction worksheets focus on taking one number away from another. This could mean taking away objects from a group or comparing two groups of objects. These worksheets help students learn to subtract numbers within 20.

Associative Property of Addition and Subtraction Worksheets

Worksheets on the associative property help students understand that the way numbers are grouped does not change the sum or difference. For example, (2 + 3) + 4 equals 2 + (3 + 4). These worksheets often involve breaking apart numbers to make them easier to add.

Commutative Property of Addition and Subtraction Worksheets

Worksheets on the commutative property teach students that the order in which numbers are added does not change the sum. For example, 4 + 5 equals 5 + 4. However, it’s important to note that this property does not apply to subtraction.

Story Problems on Addition and Subtraction Worksheets

Story problem worksheets help students apply their understanding of addition and subtraction in real-world contexts. These problems often involve situations of adding to, taking from, putting together, taking apart, and comparing.

Puzzles on Addition and Subtraction Worksheets

Puzzle worksheets provide a fun way for students to practice addition and subtraction. They can involve finding missing numbers, completing number patterns, or solving riddles.

In conclusion, Operations & Algebraic Thinking forms a crucial part of the Grade 1 Math curriculum. Worksheets are an excellent resource for students to practice these skills and reinforce their understanding.
