Students: Given mathematical statements with quantities and/or single operation phrases (addition or subtraction) on each side of the equal sign, Justify the truth of each statement using mathematical justification. Equation Students know: Strategies for finding the value of simple addition and subtraction mathematical phrases, Strategies for comparing quantities between 0 and 20, including using relational thinking, Strategies to show equality or inequality of mathematical phrases (e.g., 7 +9= 8+10 is false because if you change 7 into 8 then you must subtract 1 from the nine so this equation is false because 8 + 8 is not 8 + 10). Students understand that/are able to: Partition equal groups of numbers in different ways, Efficiently apply strategies for determining the value of simple addition and subtraction mathematical phrases, Use strategies for comparing quantities less than 20, (including using relational thinking to show equality or inequality of mathematical phrases). When groups of objects or numbers are partitioned in different ways, the total amount stays the same, The equal sign represents a relationship of balance between numerical expressions rather than performing an operation, Equalities contain expressions that represent the same amount on each side of the equal sign.
