4th grade math: what your child learns, and how to help

4th grade math is mostly about multi-digit multiplication and division, equivalent fractions, and decimals. Here is what that means, where children often get stuck, and simple ways to help at home.

What your child learns in 4th grade

Place value to 1,000,000

Read, write, compare and round large numbers. Add and subtract multi-digit numbers with the standard method.

Multi-digit multiplication

Multiply up to four digits by one digit, and two digits by two digits, using place value and area models.

Division with remainders

Divide up to four digits by one digit, and explain what a remainder means in a word problem.

Fractions

Find equivalent fractions, compare fractions with different denominators, add and subtract fractions with like denominators, and multiply a fraction by a whole number.

Decimals, angles and measurement

Write tenths and hundredths as decimals, measure and draw angles, and convert between units.

Based on the Common Core State Standards for Mathematics. Your state or school may order topics differently.

How to help at home

How Kidscient helps with 4th grade math

  • It starts from your child's level, not their grade. A short, friendly check finds what your child can already do. Many children are ahead in some topics and behind in others.
  • Homework help without answers. Your child snaps tonight's math homework and Curio helps with each problem by asking and hinting. Your child writes every answer. Code checks the arithmetic.
  • Guided lessons on a whiteboard. Curio explains each step out loud while drawing it, then asks your child to try. Lessons open level by level; at the founding beta they start around the grade 4 level.
  • Voice-first. Your child talks through their thinking, which is where the learning happens.

What math is taught in 4th grade?
In most US schools, 4th grade math focuses on multi-digit multiplication and division, equivalent fractions, and decimals. These topics follow the Common Core State Standards, which most states use or adapted.
How can I help my 4th grader with math at home?
Ask your child to estimate before multiplying. Use money to explain tenths and hundredths. When they're stuck, ask what they tried first.
My child finds 4th grade math too easy. What should we do?
Work on the next level rather than more of the same. Kidscient places children by what they can do, so a child who is ahead moves ahead.
