This math assessment focuses on evaluating and solving mathematical expressions using the correct order of operations. Kids need to remember the order by using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). Students engage with problems that require them to apply these operations in the correct sequence to solve arithmetic expressions accurately. Common Core skills covered in this unit include using parentheses in numerical expressions and evaluating expressions using the PEMDAS method.
