Below you will find the Baltimore County Public Schools standards for 4th grade mathematics. Our first math unit will focus on place value.

Students in Grade 4 should know and be able to:

Use addition, subtraction, multiplication, and division to solve a variety of problems.

Understand that multiplication can represent a multiplicative comparison.

Use manipulatives, pictures, and equations to solve multiplication and division problems.

Solve multi-step, real-world problems involving addition, subtraction, multiplication, and division.

Interpret remainders in division story problems.

Gain familiarity with factors and multiples.

Determine if numbers are prime or composite.

Generate a number or shape pattern that follows a given rule and identify features of the pattern.

Read, write, and represent multi-digit whole number up to one million.

Understand how the base ten number system works.

Use place value understanding and properties of operations to perform multi-digit computation.

Fluently add and subtract multi-digit whole numbers using the standard algorithm. Fluency, or knowing from memory, develops with the use of reasoning strategies rather than through rote memorization.*

Multiply a whole number with up to four-digits by a one-digit number.

Multiply a two-digit number by a two-digit number.

Divide a four-digit number by a one-digit number.

Use area models to show how to multiply and divide multi-digit numbers.

Extend understanding of ordering and comparing fractions.

Generate equivalent fractions.

Add and subtract fractions with like denominators using manipulatives, pictures, diagrams, numbers, and words.

Decompose a fraction into a sum of multiple fractions.

Add and subtract mixed numbers.

Solve a variety of word problems involving addition and subtraction of fractions.

Multiply a fraction by a whole number.

Understand how fractions and decimals are related.

Read, write, and represent decimal fractions up to hundredths.

Compare decimals using >, <, or =.

Solve problems involving measurement conversions and addition, subtraction, multiplication, and division.
