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

Place Value, Rounding, and Algorithms for Addition and Subtraction Task Cards
This includes over 60 math task cards and answer key. All task cards have one question with three - six possible selections (many have more than 1 correct answer.) I suggest either laminating or printing them on cardstock. I have students choose the correct answer(s) by placing clothespins on the selected choice.
Print only through page 34 if you do not want to print out the answer key.
These are great task cards for small group work, early finishers, or centers!

Multiplying -- Area Model - Partial Product - Algorithm - Distributive Property
This unit of worksheets helps students review the four different methods used to multiply a multi-digit number by a single digit. The four methods included in this worksheet are Regular Algorithm, Distributive Property, Partial Product, and Area Model. Included in this set of worksheets is a rubric for each of the four methods. I use this unit as a review giving the worksheet as homework one day a week or bi-monthly and then have students put methods on the board the next day. Unit includes 4 wo

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.
