Here are a couple of free Y3 maths worksheets to challenge children’s knowledge of addition up to 20. I suggest that you take just one set of 10 questions at a time and that a stop watch or clock is used to time how long it takes to answer the questions.
How long should they take? Well, if a child knows their number bonds, not very long at all – certainly less than a minute. Any longer, even if the answers are correct, they are probably counting on rather than knowing. Similar pages are easily created if more practice is needed.
Use these pages to try and show improvement over time, as they become more confident and more knowledgeable.
