The standards in grade 6 require that students develop a deep understanding of the meaning of equivalent.
Modeling equivalent algebraic expressions. Identify when two expressions are equivalent ie when the two expressions name the same number regardless of which value is substituted into them. For each algebraic expression identify the number of terms. The difference of a a and b b.
Level I involves only integer coefficients and constants. Allows students to develop an understanding of the meaning of equivalent expressions. An expression that contains one or more variables and may also contain operation symbols such as or -.
Requires students use of precise course-appropriate mathematical language MP6. I Model each expression using algebra tiles. Comparing Algebraic Expressions Given two algebraic expressions involving two variables we can compare whether one is greater or less than the other.
Each phrase tells you to operate on two numbers. Ii How many x tiles and 1 tiles does the expression 3x2 have. Then list the coefficients and any constant terms.
Consider the two expressions 3x 2 and 3x 6 and answer the following questions. Equivalent expressions Opens a modal Practice. They use the interactive tool to create and identify equivalent expressions.
Iii How many x tiles and 1 tiles does the expression 3x6 have. Nested fractions Opens a modal Practice. The teacher engaged in two model-eliciting activities designed for teachers by creating a library of his students work and an accompanying Ways of ThinkingWOT sheet Doerr.
Promotes coherence by highlighting prior knowledge and pointing to the mathematics that will be built from these ideas. You can also use models to determine if two expressions are equivalent. One Step Equations mini-unit focuses on distinguishing expressions and equations modeling equivalent expressions with algebra tiles determining solutions to equations and solving one step equations.
For example the expressions y y y and 3y are equivalent because they name the same number regardless of which number y stands for. Modeling Equivalent Expressions Big Mathematical Ideas In grade 6 students build on grade 5 work with numerical expressions and apply those understandings to work with algebraic expressions. Addresses standards 6EEA2 and 6EEA4.
Modeling Equivalent Algebraic Expressions Exploring the Distributive Property with Algebraic Expressions Using Order of Operations to Rewrite Simple Algebraic Expressions Using Order of Operations to Rewrite Algebraic Expressions with Four Operations Using Order of Operations to Rewrite Algebraic Expressions with Parentheses and Exponents. Expressions Modeling Equivalent Algebraic Expressions Students use an explore tool to model algebraic expressions. 3x 2 3x 6 The model for 3x 2 has xtiles and 1 tiles.
Iv Is the expression 3x 2 equivalent to 3x 6. 6EEA4 Exploring the Distributive Property with Algebraic Expressions Students use an interactive tool to explore the Distributive Property with algebraic expressions. B b divided into a a.
Level II involves rational number coefficients and constants. The quotient of a a and b b. Nested fractions Get 3 of 4 questions to level up.
A letter or symbol used to represent an. This is the foundation for writing algebraic expressions. Students will simplify algebraic expressions by combining like terms.
Up to 10 cash back The purpose of this article is to describe a middle school mathematics teachers model of his students responses to algebraic tasks involving equivalent expressions and the distributive property. If the expressions are the same or equivalent expresons we denote this equality by using. Then have students write numerical expressions from phrases without calculating them.
Ohio Department of Education Model Curriculum Instructional Strategies and Resources Have students write numerical expressions in words without calculating the value. The ratio of a a and b b. Determine if the expression 3x 2 is equivalent to 3x 6.
Model each expression using algebra tiles. The sum of a a and b b. Algebra tilesare one way to model expressions.
7p 6pc 3c - 2. We can denote the inequality between the expressions by using or symbols. For a direct link go to.
