Pairs to 10 and 20 : mix of number sentence sheets and word problems.

KS1 - mainly Year 1 or lower end Year 2 pupils who ned to practise their fluency in number pairs that make 10 or 20 and apply to missing number calculations and word problems. One sheet allows children to see the simple pattern and another sheet is jumbled to challenge those who are already confident. I couldn't find anything that ticked all the boxes I needed so I made my own little set.
I hope they help. Please comment.
