Monday we will begin to get to our 3rd way to do math problems....SOLVE
The last 2 weeks we worked on
Simplify - making a long expression shorter by combining like terms
ex. 6g + 4 + 3g - 2
9g + 2
Evaluate - Substitute number values for letters
ex. 5f - 4 when f = 5
5 (5) - 4
25 - 4 = 21
This week we will focus on
Solve - Find the value of a variable
ex. p + 14 = 20 solve for p
subtract 14 from both sides to find p = 6
We will start slow with simple one step equations. Students should become familiar with recognizing equations vs. expressions.
An expression is a group of numbers, variables, and/ or operations.
ex. 6y - 2y + 3 is an expression
An equation is 2 expressions that are equal to each other.
ex. 6y - 2y + 3 = 27 is an equation (where we could solve for y)
