Add two 2-digit numbers mentally when no carrying is needed.
Where your child meets this in real life: Mental addition of prices, scores, or 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 (no carry) into 2 steps, taught in order so each skill builds on the last.
Add two 2-digit multiples of 10 (e.g., 30 + 40 = 70)
Add two 2-digit numbers by partitioning into tens and ones (e.g., 23 + 45 = 68)
Try three free questions from our add 2-digit numbers (no 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.
Amelia has 30 stickers. Her friend Ruby gives her 40 more stickers. How many stickers does Amelia have now?
A baker made 42 scones in the morning and 36 scones in the afternoon. How many scones did she make altogether?
Matthew walked 30 metres to the shop. Then he walked 40 metres to the park. Finally, he walked 20 metres home. How far did Matthew walk in total?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Georgia collected 30 shells at the beach. Her brother Ethan collected 40 shells.
How many shells did they collect altogether?
30 + 40
Show Georgia's 30 shells as 3 tens.
Step 1 of 4
Georgia collected 30 shells at the beach. Her brother Ethan collected 40 shells.
How many shells did they collect altogether?
Georgia and Ethan collected 70 shells altogether.
The key insight: If you know 3 + 4 = 7, then you know 30 + 40 = 70!
Common mix-up: 30 + 40 = 34. This adds 30 and 4, not 30 and 40. The 40 means 4 tens, not 4 ones.
These are the misconceptions we see most often in add 2-digit numbers (no carry), including the ones our practice questions are specifically designed to catch.
Struggling with add 2-digit numbers (no carry)? The real gap is often in one of these earlier topics.
