Where your child meets this in real life: Adding prices at a shop, combining scores, or totalling measurements
Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks add 2-digit numbers (with carry) into 2 steps, taught in order so each skill builds on the last.
Add two 2-digit numbers mentally when ones digits sum to 10 or more but total stays under 100 (e.g., 47 + 35 = 82)
Add two 2-digit numbers mentally when the total exceeds 99 (e.g., 67 + 58 = 125)
Try three free questions from our add 2-digit numbers (with carry) course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
Ellie has 36 stickers. Her friend Niamh gives her 47 more stickers. How many stickers does Ellie have now?

This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.

The key insight: When digits add to more than 9, you make a new ten to carry over!
Common mix-up: 38 + 45 = 713. Writing 13 in the ones column instead of carrying the 10 to the tens column.
