For example, since 72 is a multiple of 8, we say 72 is divisible by 8. Since 72 is a multiple of 9, we say 72 is divisible by 9.
Each pair of students will need a copy of each of the three versions of the game. It is important to prepare these in advance, as the 10 cards in each game set need to be cut out prior to play.
If possible, copy each game set onto a different color of paper. This will help keep the different versions of the game separate from each other. Ask students to work in pairs. Distribute Expression Matching Game 1 and introduce Game 1 as follows.
The matching game consists of 10 cards. Five of the cards have a word phrase on them, and five have a mathematical phrase or expression on them. The goal is to match each word phrase with the corresponding mathematical expression.
To begin, put all 10 cards on your table with the writing showing. Work together to find all of the matching sets of cards. Remind students that the order of a subtraction problem is important.
Now, distribute Expression Matching Games 2 and 3 to each pair of students. For Game 2, you may want to suggest students place the 10 cards so the writing cannot be seen. Students may then take turns flipping over two cards.
If the two cards they uncover are a match, they keep that pair of cards. The student with the most matches when the game is over is considered the winner.
A third Expression Matching Game is also provided. The difficulty increases slightly from Game 2 to Game 3.
With 5 to 8 minutes left in the class period, distribute an index card to each student. Ask students to write a mathematical expression to represent this phrase. Review the exit slips before the next class period to identify common errors students are making and specific students that need extra support.
Use the following strategies and activities to meet the needs of your students during the lesson and throughout the year. To refresh students on lesson concepts during the year, try Video Tutorial—Interpreting Numerical Expressions.
A video tutorial is provided at this site.
Students can practice writing and interpreting expressions using this online activity: Students ready for an additional challenge will find this Web site helpful. This online activity engages students in writing equations, not simply expressions as in this lesson: Video playback may not work on all devices.
Instructional videos haven't been assigned to the lesson plan.Write an expression for your classmates to simplify using at least three of the following: (a) Groupings (parenthesis, brackets, or braces), (b) Exponents, (c) Multiplication or division, and (d) Addition or subtraction.
There are several types of symbols we will be using. There are four basic arithmetic operations: addition, subtraction, multiplication, and division.
We’ll list the symbols used to indicate these operations below. Translate each English phrase into an algebraic expression: ⓐ the difference of \(14x\) and 9 ⓑ the quotient of \(8y^2. An important difference between fractions and rational expressions, though, is that we must identify any values for the variables that would result in division by 0 since this is undefined.
These excluded values must be eliminated from the domain, the set of all possible values of the variable. algebraic expression constant difference equation inverse operation phrase product quantity quotient solution substitute write an algebraic expression for each of the missing results.
