# 3.OA.D.8 Lesson Plans

Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding. (This standard is limited to problems posed with whole numbers and having whole-number answers; students should know how to perform operations in the conventional order when there are no parentheses to specify a particular order (Order of Operations).)

## TOPICS RELATED TO TWO-STEP PROBLEMS

### What is a two step equation?

A 2-step equation is an algebraic equation that takes you two steps to resolve. you've solved the equation while you get the variable through itself, with out a numbers in the front of it, on one side of the identical signal.

### What is a one step problem in maths?

A one-step equation is an algebraic equation you can resolve in best one step. once you've solved it, you've got determined the cost of the variable that makes the equation real. to remedy one-step equations, we do the inverse (contrary) of anything operation is being completed at the variable, so we get the variable by means of itself.

### What are multi step math problems?

A multi-step- word problem is sort of a puzzle with plenty of portions. multi-step word problems are math issues that have multiple operation. an operation is addition, subtraction, multiplication or division.
