Remind students that the order of a subtraction problem is important. For Game 2, you may want to suggest students place the 10 cards so the writing cannot be seen. Work together to find all of the matching sets of cards.
Ask students to work in pairs. Students can practice writing and interpreting expressions using this online activity: To refresh students on lesson concepts during the year, try Video Tutorial—Interpreting Numerical Expressions.
Students may then take turns flipping over two cards. To begin, put all 10 cards on your table with the writing showing. This online activity engages students in writing equations, not simply expressions as in this lesson: The matching game consists of 10 cards.
If the two cards they uncover are a match, they keep that pair of cards. Now, distribute Expression Matching Games 2 and 3 to each pair of students.
Use the following strategies and activities to meet the needs of your students during the lesson and throughout the year. Five of the cards have a word phrase on them, and five have a mathematical phrase or expression on them.
Ask students to write a mathematical expression to represent this phrase. A third Expression Matching Game is also provided. The difficulty increases slightly from Game 2 to Game 3.
A video tutorial is provided at this site. Distribute Expression Matching Game 1 and introduce Game 1 as follows. Students ready for an additional challenge will find this Web site helpful.
Review the exit slips before the next class period to identify common errors students are making and specific students that need extra support. Each pair of students will need a copy of each of the three versions of the game. The goal is to match each word phrase with the corresponding mathematical expression.
It is important to prepare these in advance, as the 10 cards in each game set need to be cut out prior to play. This will help keep the different versions of the game separate from each other.
With 5 to 8 minutes left in the class period, distribute an index card to each student. Video playback may not work on all devices. If possible, copy each game set onto a different color of paper. The student with the most matches when the game is over is considered the winner.Words to match the expression 24 - (6 + 3) is given as follows: "the difference of 24 and the sum of 6 and 3"/5(4).
Present the expression 7 + 8 × 3, and ask students to write a word phrase describing this expression. Also, present the word phrase “4 less than the product of 9 and 2”.
Ask students to write a mathematical expression to represent this phrase. Write an expression to match the words given.
Note: Parentheses are not needed to show multiplication or division happening first, because the rules for the order of operation already say that they come before any adding or subtracting.
Cooperative learning activity where students match an algebraic expression to a story problem. Once all expressions have been matched, student teams are given the value of the variable with a clue card. Then they use the substitution property to solve word problem.4/5().
