Unit 4 Decimal Computation
Learning Outcomes
• Use estimation as a means for checking for reasonableness when computing with decimals • Multiply decimals (through thousandths) • Divide decimals (decimals through thousandths divided by divisors that include onedigit whole numbers or decimals expressed as tenths) • Create and solve single and multistep practical problems involving addition, subtraction, and multiplication of decimals • Create and solve singlestep practical problems involving division of decimals • Use multiple representations to model multiplication and division of decimals and whole numbers 
Essential Questions
•How do the strategies we use to compute with whole numbers relate to computing with decimals? • How can estimation and/or benchmark numbers be used to determine the reasonableness of answers? • What representations could be used to improve your efficiency with computing decimals? • How can you use properties to help you compute with decimals mentally? • What questions do you ask yourself when you are solving problems and reflecting on your solutions?

Estimation 
A tool used to find a near solution. Estimation is used to to precheck solutions, closely solve equations and plan for real life situations.

Reasonable 
Estimation must be reasonable, or thoughtful.
Considering the reason for estimation will help you in deciding how "close" an estimate needs to be. 
Quotient 
The solution to a division problem

Product 
The Solution to a multiplication problem

Expression 
Numbers, symbols and operators (such as + and ×) grouped together that show the value of something.
