Partial Sums Algorithm Practice
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

Roll, Represent, and Solve
Students are expected to create and recognize many different representations of operations. Including strip diagrams, number lines, decomposing numbers, and standard algorithm each day can be very time-consuming and even a little boring. This is a center activity for students to practice their representations in a more randomized and fun way. Students use task cards or other review type problems, then roll a die to determine how they are going to represent their problem. A recording sheet is

CGI- Strategy Practice for Addition
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.

Adding and Subtracting by Multiples of 10
One way to add and subtract mentally is to understand the role place value plays. Too often, students are taught only one way to add and subtract by using regrouping as the algorithm. While this knowledge is important, having the number sense to add and subtract two and three digit numbers (or more!) helps the student to visualize what he or she is doing when problem solving mathematically.
This set of worksheets gives a brief explanation and example of the thought process behind adding and su
