Below are a list of the Common Core math standards that this unit plan is aligned with:
1ST GRADE COMMON CORE STANDARDS
Use addition & subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, (e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem).
Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20.
Understand the meaning of the equal sign, & determine if equations involving addition and subtraction are true or false.
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
2ND GRADE COMMON CORE STANDARDS
Use addition & subtraction within 100 to solve one & two-step word problems involving situations of adding to, taking from, putting together, taking apart, & comparing, with unknowns in all positions.
Fluently add and subtract within 20 using mental strategies.
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends.
Add up to four two-digit numbers using strategies based on place value and properties of operations.
