Fourth grade builds critical math foundations: multi-digit arithmetic, fractions, decimals, measurement, and basic geometry. Parents should request lesson plans, maintain regular communication with teachers, and use short daily practice and reputable online resources (e.g., Khan Academy, PBS Kids, Mathigon, IXL) to reinforce learning. When consistent effort and teacher coordination don't close gaps, consider targeted tutoring or programs.
Why fourth grade math matters
Fourth grade is a foundations year. Students move from basic operations to multi-digit arithmetic, begin working with fractions and decimals, and use measurement and geometry in more complex ways. These skills set the stage for middle school math and everyday problem solving.
Know the standards and the classroom plan
Ask your child's teacher for the year-long or unit lesson plan early in the school year. Many U.S. districts base fourth grade expectations on the Common Core State Standards, but states and districts vary. Reviewing the plan helps you spot upcoming topics and schedule support if your child needs it.
Schedule regular check-ins with the teacher: brief emails, conference nights, or quick phone calls. Clear communication helps you catch gaps early and coordinate help - tutoring, targeted practice, or classroom supports.
What fourth graders commonly learn
Typical fourth grade topics include multi-digit multiplication and division, number place value, fractions (equivalence and basic operations), decimals to the hundredths, basic factors and multiples, measurement and unit conversion, and introductory geometry and angles. Teachers also build reasoning and problem-solving skills through word problems and simple algebraic thinking.
(Standards can differ by state - check your district's guide for precise topics.)
Use short, focused practice at home
Ten to twenty minutes of daily practice is more effective than longer, infrequent sessions. Focus on number sense: mental math, multiplication facts, and fraction models. Use real-life contexts - cooking measurements, money, or maps - to make concepts concrete.
Choose resources and games wisely
Combine free and paid options depending on your needs. Free, reputable resources include Khan Academy (standards-aligned lessons and practice) and PBS Kids math games for younger reinforcement. Mathigon offers interactive visual explanations and activities. Subscription services such as IXL provide structured practice and diagnostics. Look for resources that explain concepts, not just give answers.
Classroom teachers often use interactive games and group activities to increase participation. At home, use short, game-like activities to build motivation: timed recall, fraction matching, or measurement scavenger hunts.
When to get extra help
If your child avoids math, loses confidence, or struggles with basic steps after consistent practice and teacher communication, consider extra support. Options include small-group tutoring, after-school programs, or targeted online instruction. Early intervention prevents gaps from widening.
Keep it positive and practical
Math skills build on prior learning. Praise effort and progress more than correctness. Focus on one skill at a time, give specific feedback, and celebrate improvements. With steady, short practice and clear communication with the teacher, parents can help fourth graders gain the skills they need for success.
