We’ve been using Calculadders with all of our kids this year to make sure that they have a solid foundation in fundamental math skills. I really like the philosophy behind the development of Calculadders, that encourages mastery – both speed-wise and accuracy-wise – in order to prepare students for success with more advanced math. It’s a great approach that we can use with all levels simultaneously and get done in a relatively short amount of time each day (or whatever days we are focusing on math). It’s also easy to time everyone, track their errors, and generate reports with their overall performance.
When any of the kids run into difficulty with a level and end up stuck there, it’s an indication that they need additional practice on that skill. I was really excited to find a resource today where you can enter your own parameters and generate endless worksheets as pdfs that can be quickly printed and distributed to students to give them ample reinforcement in the area where they are struggling. For example, just click Multiplication Worksheets and it takes you to a page where you can specify what to include on the worksheet. I know I’ll be visiting this site often!
