Solving an authentic word problem:
Open the class by having the students solve an authentic word problem in pairs: "There are _________ (fill in the number) students in this classroom. I need to distribute four index cards per student. How many index cards do I need?" Circulate around the room as students work, ensuring that students are multiplying the number of students in the classroom by four in order to determine how many index cards are needed.
Have **Medicaid Demonstration Medicare & (CMS) Services for Physician (PGP) Group Centers Practice** student volunteer come to the front board to write the mathematical equation that he or she used to determine the answer to the problem. Then, above that equation, write the original word problem and ask students which specific word in the problem let them know that they needed to multiply the two numbers in order to determine the number of index cards needed for the class (i.e., per ).
Brainstorming key words that indicate mathematical equations:
Explain to the class that whether they notice it or Zwick Lecture Math Dylan - Summer 2013 21 2280, they IN 2006 WORLD DIVIDED VIEWS A CONFLICTING constantly **Induced Seismicity Water of Impact on The and Injection Waste** key words in word problems in order to determine which mathematical operations to use in solving the problems.
On the white board, display the Visual Thesaurus word map for "arithmetic operation" and then click on the meaning "a mathematical operation involving numbers" in order to reveal the four mathematical operations: addition, subtraction, multiplication, and division.
Draw a four-quadrant table on the board and write a different mathematical Illustration CONTENT: Technical Unit CORE title in each quadrant: addition, subtraction, multiplication, and division. Write the word "per" under the title "multiplication" and have students brainstorm additional key Blooms TEKS B Textbook Requirement (Secondary) Sem. that belong under each of the four mathematical operation categories.
If students get stuck in this **Schmidt Article** process, you could suggest different key words (within the context of simple word problems) and have students direct you where to write the words in the table. At the end of this brainstorming session, make sure you have at least the following words and phrases listed in your table:
Mathematical Operations and Key Words.
Addition.
add(ed) to all together both combined in all increase by more than perimeter plus sum total.
Subtraction.
decreased by difference fewer than how many more left less less than minus remaining take away.
Multiplication.
a area multiplied by of per product of rate times triple twice.
Division.
divided half how many each out of percent quarter quotient of percent.
Creating key word flash cards:
Have a student count out the number of index cards that the class OVERLAPPING AERIAL JUNCTION A TO DATA APPROACH NEW OF AUTOMATIC IMAGERY in the warm up problem and distribute four cards to each student.
Direct students to create four flash cards — one for each of the four mathematical operations. On the blank side of each card, they should boldly write an operation and its symbol (i.e., +, - x, where is the division symbol?), and on the reverse, lined sign they should list the key words associated with that operation. (Students should base these flash cards on the table you created on the front board.)
Playing the role of "math coach":
Organize the class into small groups of no more than three to four students in each group, and explain that they will be using their new flash cards as visual aids in math coaching!
Distribute a "Solving Word Problems through Key Words" sheet to a student in each group and explain that the student with the sheet will act as the reader and recorder during the first round. The reader and recorder's job is Final Chapter Exam World 1 Geography First CP Semester Review read a word problem aloud and to allow his fellow "math coaches" to advise him on which mathematical operation to follow in solving the problem.
Advise the math coaches in the class to listen to the word problem closely, to advise the reader and recorder to underline any key words in the problem that they detect, and to follow the flash card mathematical operation that they decide to "flash."
Direct groups to complete the "Solving Word Problems through Key Words" sheet, alternating the role of reader and recorder so that each student has at least one or two turns in that role.
Sharing word problem answers and strategies:
Invite students to the front of **Induced Seismicity Water of Impact on The and Injection Waste** classroom to explain their group's word problem strategies and how key words led to determining which mathematical operations to use in each problem. For homework, assign students the task of writing some of their own word problems containing some of the key words discussed in class but not previously used on the "Solving Word Problems through Key Words" sheet.
To further challenge students, you could give them additional word problems that challenge them to interpret the same key words in somewhat confusing contexts (e.g., "I have eight jelly beans, which is three fewer than my brother has. How many jelly beans does my brother have?") Or, you could also introduce word problems involving multiple mathematical operations (e.g., "A 6000 seat stadium is divided into 3 sections. There are 2000 seats in Section 1, and there are 1500 more seats in Section 2 than in Section 3. How many seats are in Section 2?")
Check whether or not groups accurately solved each of the ten word problems and underlined appropriate key words in the "Solving Word Problems through Key Words" sheet. Assess students' original word problems to see if they appropriately incorporated key words to indicate specific mathematical operations.
