UK Year 3 • Class 3 • Ages 7-8
Start Practicing
Third grade is a pivotal year for mental math development. Students transition from basic addition and subtraction to mastering multiplication facts and working with larger numbers. Mental maths for class 3 focuses on learning the 3, 4, and 8 times tables while continuing to build fluency with the 2, 5, and 10 tables from Grade 2. Students also develop strategies for mentally adding and subtracting three-digit numbers. By the end of Grade 3, children should fluently recall multiplication and division facts within 100, setting the stage for more complex mathematical operations.

FAQ
What times tables should a Grade 3 student know?
By the end of Grade 3, students should know their 2, 3, 4, 5, 8, and 10 times tables fluently. They should be working toward knowing all products of two one-digit numbers from memory, which is typically mastered by the end of Grade 3 or early Grade 4.
How do I teach mental maths for class 3 addition?
For 3-digit mental addition, teach place value strategies: add hundreds first (300+400=700), then tens (50+30=80), then ones (2+5=7), and combine (787). Also teach compensation strategies like adding 299 by adding 300 and subtracting 1.
My 8 year old is slow at times tables. What should I do?
Focus on one times table at a time until it's automatic. Use daily 5-minute practice sessions with our online trainer. Look for patterns (4× is double 2×, 8× is double 4×). Make it competitive with personal best times. Consistency is key—daily practice beats weekly cramming.
