Math 6 students worked with Lesson 3.4: Write Algebraic Expressions. During this lesson, students worked to:
- write an algebraic expression to model a pattern.
- write an algebraic expression from a word phrase.
- use mathematical language when identifying parts of an expression.
Math 6+ students continued their work with inequalities. Today Mr. Giomini worked with writing and solving inequalities from story problems.
Standards addressed/assessed today in class:
- Math 6:
- Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. For example, describe the expression 2 (8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.
- Write expressions that record operations with numbers and with letters standing for numbers. For example, express the calculation "Subtract y from 5" as 5 - y.
- Math 6+:
- Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.
- Write an inequality of form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
