Mental Computation: Adding 2-digit Doubles and Near Doubles

In Maths groups we have been working on mental computation strategies for addition. My group has been working on adding 2-digit doubles eg. 20 + 20. Students have picked up the concepts very quickly and have powered through the work I have provided. As a result, I have developed a number of resources to use with this concept in order to ensure that the new learning is consolidated. While mostly related to Year 2 (particularly in terms of the Australian Curriculum and Common Core State Standards in the USA) it could be useful for Year 3 teachers when revisiting mental strategies.

This is my latest resource to be added to Teachers Pay Teachers. At 40 pages, it ended up being quite a bit of work - particularly when I forgot to save a day's work before shutting down the computer! (Yes, I still make stupid mistakes from time to time!) So, if you like the look of it, please recommend it to any of your friends who teach Year 2/Grade 2.

From a technical perspective, this new resource contains some of my unique clipart, borders and fonts. Still amateur, but improving, I think. The borders were actually much easier to insert than I first imagined, and it's nice to see my 'Me' font and 'Cutesy' font on something I have created.
