Partial Sums Algorithm Practice

Created by

If you use Everyday Mathematics, then you know how difficult it is for some children to learn the Partial Sums Algorithm. You break it down, think they have it, but find they have a hard time transferring the skills independently. DIFFERENTIATION is the key! These partial sums practice sheets are differentiated to give your kids what they need, and to progress the reluctant learner through 4 phases as your gradually release responsibility: •The first five sheets are colored coded and gridde

CGI- Strategy Practice for Addition

Created by

California Resources

After teaching 2nd grade for several years, I observed that my students were confusing the following strategies: direct modeling, counting on, counting back, and using invented algorithms. Therefore, I created this resource to model the different strategies for students. This product is practicing addition from 1 + 2 up to 1+ 10 for the number sets 1-10.There are 90 different problems categorized in numerical order. This product can be used for direct instruction, practice, and/or assessment.
