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

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.

Unit 1: Number and Operations in Base Ten - 3rd grade
Standards:
MCC.3.NBT.1 Use place value understanding to round whole numbers to the nearest 10 or 100.
MCC.3.NBT.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
This is a CFA pr/post test I created for the standards above. I give the test at the very beginning and then give the post at after I teach the unit.

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
