Basic Multiplication Fact Fluency Practice
Multiplication fact fluency is a BIG topic in the upper elementary grades. It is a foundation that higher level math computations require. Students that lack fact fluency struggle to complete multiple step algorithms precisely. additional multiplication work leaves room for error in lengthy equation problem solving. Students that have their basic multiplication facts memorized are more successful and confident in math class. This resource allows students the practice required to conquer math fa

Partial Quotient Division Poster
Partial Quotient Division Poster
This Partial Quotient Division Poster gives step by step instructions for your kiddos to learn Partial Quotient Division. I use this to hang on my wall to remind my students of the steps for Partial Quotient Division. Some of my students do not understand the "long division" algorithm. This helps A LOT!
Check out my animated PowerPoint presentation that walks you and your students through the steps more thoroughly. Partial Quotient Division PowerPoint

Multiplication Strategy charts
This is a set of charts I made to compliment the teaching of multiplication using thinking strategies and writing them down. Each chart explains the steps and provides a visual representation. I print them in A3 size.
the strategies include:
The "Compensate Strategy"
The "Split Strategy"
The "Area Model" and
The "expanded algorithm".
