4th Grade Math Concepts

Place Value and Expanded Form

In 4th grade, we explore place value, which is like knowing the special job each digit has in a number. When we write numbers in expanded form, we break them down into their parts, like 365 becomes 300 + 60 + 5.




Multiplication and Long Division

Multiplication helps us quickly find the total when we have equal groups of numbers. For example, 4 times 3 equals 12. Long division is like a more organized way to share and split numbers, making sure everyone gets a fair share.




Decimals and Decimal Place Value

Decimals are like special points in numbers, showing values smaller than a whole. In 4th grade, we learn to understand decimal place value, which helps us work with numbers like 0.25 or 3.75.




Fractions and Operations with Fractions

Fractions continue to be important. We learn to add, subtract, multiply, and divide them. For example, adding 1/4 and 1/3 involves finding a common way to share and combine pieces.




Geometry: Lines, Angles, and Symmetry

In geometry, we explore lines and angles more deeply. Lines can be parallel or intersect, and angles can be acute, right, obtuse, or straight. We also learn about symmetry, which is like a shape being balanced when you fold it in half.




Measurement: Converting Units and Word Problems

We get better at converting units to measure length, weight, and volume. For instance, we learn how many centimeters are in a meter. We also solve word problems that involve measurements, helping us understand the real-world use of math.
