For: Grade 4 students (ages 9–10) practicing arithmetic fluency

Math Games for Kids Grade 4 — Free Online

If you want a free online math game that actually builds Grade 4 arithmetic fluency — not just gamified time-wasting — Math Trainer is the right starting point. The game cycles through addition, subtraction, multiplication, and division at Grade-4 difficulty (numbers up to 100, two-digit multiplication facts, division within 100). No paywalls, no ads, no account. Works on any device with a browser — Chromebook, iPad, parent's phone.

How it works

Each round shows one arithmetic problem (e.g. 7 × 8 = ?). The student taps the correct answer from four choices. Right answers add 1 point and increase difficulty slightly; wrong answers show the correct value before moving on. After 10 problems, the score and average response time are displayed. Best for 5–15 minute focused practice sessions.

Skills covered

• Multiplication tables 1–12 to automatic recall
• Two-digit addition and subtraction with regrouping
• Division facts within 100
• Mental math speed (the game tracks your time per round)
