How do you represent integers for these word problems???
Consecutive Integers:x = 1st integerx + 1 = 2nd integer
x + 2 = 3rd integer x + 3 = 4th integer
and so on...and so on...
Students will be able to analyze and solve verbal problems whose solution requires solving a linear equation in one variable.

Consecutive Even/ Odd Integers:x = 1st even/ odd integer
x + 2 = 2nd even/ odd integerx + 4 = 3rd even/ odd integerx + 6 = 4th even/ odd integer
and so on... and so on...
Students will be able to analyze and solve verbal problems whose solution requires solving a linear equation in one variable.
Notice you always add 2 (+2) to get to the
next even or odd integer.
Think about it. What do you add to 5 to
get to the next odd integer?
What do you add to 24 to get to the
next even integer?
