Addition Week 1 - Full week of worksheets with answers differentiated KS2 Year 3,4,5

Here is an Addition worksheet pack I have created. I have included a whole week of worksheets with answers to allow children to self-assess. I have put year 3, 4, or 5 as it really depends on where your class are at and children's individual needs. In regard to the national curriculum, this would be aimed at year 4. It includes place value headings and the use of chilli challenge for children to select their own difficulty. I hope you like it! Your feedback is always welcomed. Thank you.
