There are two sets of worksheets, one on addition and the other on subtraction of 2 digit numbers.
Within each set a learning path has been created so that your students can build their skills and knowledge one step at a time through differentiated worksheets as follows:Â Â

• No regroupingÂ

• RegroupingÂ  once - 2-Digit plus a 1 digit number

• Regrouping twice -Two 2-Digit numbers

• Adding four 2 Digit numbers

SubtractionÂ

• No regrouping

• Regrouping - 2-Digit minus a 1 digit number

• Regrouping -Two 2-Digit numbers

How many worksheets are in each set ?

A lot .... almost unlimited.Â

How is this possible ?
At the bottom of each page there is a button which when clicked randomises all the numbers on the page thereby creating a completely new worksheet. You can create as many new worksheets as you need at each level.Â  Keep the skill alive throughout the year. Produce a new worksheet for classwork and homework practice; use as a filler activity; leave a straightforward activity for a replacement teacher or even give each pupil or groups of pupils in your class individualized sets of questions either all at the same level or differentiated according to their progress. Need to revise a level ? No problemÂ  .... click the appropriate button and you have a new worksheet. There will certainly be enough to ensure fluency in this topic.

Yes. These can be found on the second page of every worksheet,Â  and are automatically generated every time you create a new worksheet.

Note
These resources are PDF documents and work with the officialÂ  Adobe Acrobat Reader on Windows or Mac computers, with the randomising buttons also working via a touchscreen or on an Interactive Whiteboard.
