Station 2 Independent Practice: Algebraic and Numerical Expressions Distribute Handout 7.3: Algebraic and Numerical Expressions. Tell students they will write an algebraic expression for 5 situations and write numerical expressions for the volume of two cubes and the area of three squares.
So this right over here is the numerical expression that models the situation without performing any operations. We, of course, could then actually calculate this. He has 9 marbles before tripling. And then you multiply it by 3 and he has 27. But this is what they're asking for. They want us to write this expression.
We then walk through writing numerical expressions for the following: a) twice the sum of five and seven. b) three times the result of subtracting four from nine. c) two less then the result of dividing fifteen by three. d) one more then five groups of two-fifths.
KS3 Programme of Study Statements-- Model situations by translating them into algebraic expressions.-- Use and interpret algebraic notation.-- Substitute numerical values into expressions.-- Simplify and manipulate algebraic expressions to maintain equivalence by collecting like terms. Use the concept and vocabulary of multiples.
The term numerical expression is made up of two words, numerical meaning numbers, and expression meaning phrase. Thus, it is a phrase involving numbers. Thus, it is a phrase involving numbers. A numerical expression in mathematics can be a combination of numbers, integers combined using mathematical operators such as addition, subtraction, multiplication, or division.
