This BUNDLE is designed for Year 3 students where they are required to be able to add and subtract numbers with up to three digits, using formal written methods of columnar addition and subtraction.

As you will see in the description of each resource differentiation is a major feature allowing you to pick and choose the level of practice suitable for all your students.

Because (at the click of a button) you can randomize the numbers on every worksheet, a student can repeat a level of worksheet more than once, so that they build confidence , step by step, over whatever time period is needed.
