2. Presentation of New Information or Modeling: 10 min Essential question: o Why is it important to follow the order of operations? What is the correct order to solve equations using the order of operations? o P = parenthesis o E = exponents o MD = multiplication and division (whichever is first from left to right) o AS = addition and subtraction (whichever is first from left to right) Parentheses: parentheses are used in mathematical expressions to denote modifications to normal order of operations (precedence rules). 3. Guided Practice: 10 min Write the following problem on the board: 4 + 5 × 3
Solve the equation using the wrong and correct way.Student A4 + 5 × 9 × 27Student B4 + 5 × 4 + 1519Ask questions from students to see if the can determine why there are two different answers to the same problem. Explain to them that the order of operations is very important in solving problems. Remind the children that multiplication and division have to be solved in order of what sign is first. The same thing with addition and subtraction. 3 3 3
Pedagogical Strategy (or Strategies): Direct instruction: teacher will model and explain the order of operations to the students Partner work: students will work with partners to complete The Target Number Dash. Technology Exploring Order of Operations- This interactive mathematics resource allows the user to explore the order of operations (brackets, exponents, multiplication, division, addition and subtraction). The resource also includes print activities, solutions, learning strategies, and a math game. There are 5 different levels in which students can explore problems based on their needs and understanding. ?
