Math Games for Teachers

Grade 5 - Number

Standard 5.N.4 - Round the numbers in an equation to a specified place value then evaluate.

Included Skills:

Develop and apply personal strategies for estimation and computation including:
front-end rounding
compensation
compatible numbers
Describe a situation relevant to self, family, or community for when estimation is used to:
- make predictions
- check reasonableness of an answer
- determine approximate answers.
Develop and use strategies to estimate the results of whole-number computations and to judge the reasonableness of such results.
Critique the statement "an estimate is never good enough".
Identify and describe situations relevant to self, family, or community when it is best to overestimate or when it is best to underestimate and explain the reasoning.
Determine an approximate solution to a problem not requiring an exact answer and explain the strategies and reasoning used (e.g., number of fish, deer, or elk required to feed a family over a winter; amount of money a family spends on groceries).
Explain estimation and computation strategies, including compatible numbers, compensation, and front-end rounding, and how each strategy relates to different operations.
Identify if a strategy used in solving a problem involved estimation or computation.
Apply and explain the choice of estimation or computation strategy such as compatible numbers, compensation, and front-end rounding.
