6 th Grade Unit 3 Vocabulary

This unit covers essential sixth-grade vocabulary related to algebraic expressions, rates, patterns, and variables. An algebraic expression employs letters to represent numbers, and examples illustrate their application. The text explains the structure of cells, columns, and rows in mathematics, as well as formulas for calculating area and perimeter. Concepts like general patterns, special cases, square roots, and unit rates are discussed. This unit aims to clarify these terms to enhance students' understanding of fundamental math principles.

  1. 6th Grade Unit 3 Vocabulary By Drew Levine

  2. Algebraic expression • An algebraic expression is when you can use any numbers for that problem and you replace them with letterers • Examples • Ax0=0 • Ax1=A • (A+A)x3=3x(A+A)

  3. Cell, Column and rows Cells are the boxes. a column is the part going up and down. Rows are the boxes that go side to side.

  4. Formula • RxRx3.14=A • Lx2+hx2=perimeter

  5. General pattern • A general pattern is when the sum is different then the sum for an • Example • 90+(-90)=0

  6. Rate Rates are used to show date over time also to can compare different things in the corner you can see they are comparing 3 different things

  7. Special case • A special case is an exception to a rule or an easier way to solve a problem. • X2- 9=(x+3)(x-3)

  8. Square root • The square root is when you take a number and find that it multiplied by its self = that number. Examples • The square root of 9 is 3 • 100 is 10 • 81=9 • 64=8

  9. Unit rate • The denominator of a fraction is 1 of something. • For example, I get paid $8.51 an hour 8.51/1 • My car goes 70 miles an hour.70/1

  10. variable • A variable is a symbol or letter that is used to represent a number in a math equation. • X+9=12
