Algebra- Writing mathematical phrases using letters to represent numbers
eg. n+3 = 143x = 18
Variable- a letter that represents a number in an equation or expression
eg. n+11=20 (can be n, x, p, z, or any letter)
Constant- the integer in an algebraic expression or equation
eg. 18+n =35
Expression- Pattern (many answers)
eg. 5n
With and Without tiles
1st: Isolate the variable
2nd: Cancel the constant using zero pair
3rd: Balance (do the same thing to the other side)
4th: Verify to check
