4th Grade Mathematical Standards

Number Sense

2.0 Students extend their use and understanding of whole numbers to addition and subtraction of simple decimals.

2.1 estimate and compute the sum or difference of whole numbers and positive decimals to two places

2.2 round two-place decimals to one decimal or the nearest whole number and judge  the reasonableness of the rounded answer


3.0 Students solve problems involving addition, subtraction, multiplication, and division of whole numbers and understand the relationships among the operations.

3.1 demonstrate understanding of, and the ability to use, standard algorithms for addition and subtraction of multi-digit numbers

3.4 solve problems involving division of multi-digit numbers by one-digit  numbers



Mathematical Reasoning

1.0 Students make decisions about how to approach problems.

1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, sequencing and prioritizing information, and observing patterns

1.2 determine when and how to break a problem into simpler parts


2.0 Students use strategies, skills, and concepts in finding solutions.

2.1 use estimation to verify the reasonableness of calculated results

2.2 apply strategies and results from simpler problems to more complex problems

2.4 express the solution clearly and logically by using appropriate mathematical notation and terms and clear language; support solutions with  evidence in both verbal and symbolic work
