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:

Subtraction Algorithm Exploration
This worksheet helps students explore different approaches to subtracting numbers with multiple place values (regrouping). It is Jack Sparrow themed and I always make my kids speak pirate during the lesson. At the bottom of the sections are hand signals to give you ideas about motions that you can use to accompany chants. Enjoy! This item has been reloaded in both PDF and Word format.

Integers 07 - Subtracting Positive and Negative Integers Using an Algorithm
Subtraction is the opposite of addition. If adding a positive integer results in a greater number, then subtracting a positive integer results in a lesser number. If adding a negative integer results in a lesser number, then subtracting a negative number results in a greater number.
Subtracting a negative is the only thing today that is new. We want students to conceptualize that taking away a negative, debt for instance, results in a greater number. We will introduce a rule for when we se

Two Digit by Two Digit Multiplication Worksheet
This is a 20 question worksheet.
Questions 1-10 are meant to be solved using expanded algorithm (arrays, area models and place value charts are suggested in the directions)
Questions 11-20 are all two digit numbers multiplied by multiples of ten. These are meant to be solved using the shortcut method.
I use this worksheet as a review for these strategies before teaching my fourth graders standard algorithm.

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.
