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.
