Describe mathematics relationships using expressions, equations, and visual representations.


Remarks


Example: Mr. Sims has 168 oranges. He wants to pack them into boxes with 28 in each box. How many boxes does he need? Use pictures or diagrams to show what is happening in the problem. Record your solution with equations.

 

Example Alex is 4 years older than twice as old as Sam What expression gives Alex's age if you use the variable "S " to represent Sam's age?

    Clarification :
    Students will translate a written description or a graphic to an expression or equation or translate an expression or equation to a written or graphic description to solve a real-world problem.

    Students will identify a missing number or element in a numeric or graphic relationship.

    Students will describe or generalize the rule of a visual relationship using an expression, equation or description of the graphic.
    Content Limits :
    Items must use rules or relationships that involve only one operation or a one-step function.

    A relationship must be defined in words, or at least three examples of the relationship must be provided.

    Relationships involving multiplication or division are limited to the multiplication facts of 0 × 0 through 12 × 12 and the related division facts.

    Items may include only one variable.
    Stimulus Attributes :
    Items may be set in a real-world or mathematical context.

    Relationships may be shown as lists or in function tables.

Lesson Plan

Name Description
"Bar Model Math" - "Twice" as Nice

In this lesson students will solve real world problems that have multiplicative comparisons in them. They will use the strategy of bar models to solve the problems.

Teaching Idea

Name Description
True, False, and Open Sentences

"Students first explore arithmetic sentences to decide whether they are true or false. The lesson then introduces students to sentences that are neither true nor false but are algebraic equations, also called open sentences, such as x + 3 = 7 or 2 x = 12." from Math Solutions.
