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

2 x 1 and 3 x 1 Digit Multiplication Quiz
This is a 2 x 1 digit and 3 x 1 digit multiplication quiz using the box method and the algorithm. This is a great worksheet for both re-teaching and also extension. If students are struggling, focus on them using the box method and helping them remain organized if their work. If they have a solid understanding of multiplication and are fluent with the box method, encourage them to work more on the algorithm. Students can also be encouraged to complete the box method first and then use the algori

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.

G1: VIDEO and Google Form Multiply 2x1 and Multiples
This lesson focuses on multiplying 2-digit by 1-digit numbers and introduces the concept of multiples. Students will learn two methods for solving multiplication problems. The first is the traditional algorithm, where numbers are written vertically and multiplied step by step. The second is the box method, which uses expanded form to break the numbers apart and multiply in sections. ______________________________________________________________________________________________ Video Tutorials – G

Multiplication and Division Quiz
This is a differentiated multiplication and division quiz. The multiplication problems are two digit by two digit, and the division problems are dividing a 3 digit by a 1 digit number. The quiz is differentiated because it includes multiple choice answers for the first 4 problems. It then becomes a bit more challenging when the students are asked to solve with no multiple choice answers. Finally the quiz ends with a two part brief constructed response in which they have to determine if they need
