Long Division with Purpose — Hands-On Manipulatives + Biblical Fairness Grade 4
Help fourth graders understand long division before the algorithm using concrete manipulatives and clear visual routines. Students model equal groups with base-ten blocks, sketch what they built, then bridge to Divide–Multiply–Subtract–Bring Down with an anchor chart. Faith tie-ins highlight generosity, fairness, and wise stewardship, making math meaningful and memorable. Perfect for whole-class launch, small-group intervention, or sub-ready plans.

Partial Product Multiplication
Page 1: Fourth grade Everyday Math introduces the partial product algorithm for multi-digit multiplication using a game called "Tag Team Wrestling". My students love the game, but many have a hard time lining up the numbers of the partial products. So I created a worksheet that has boxes instead of lines for the partial products. Page 2: I also created a template that can be used to transition students more gradually to the partial product method. It has less prompts than "tag team wrestli

Trading Tens: Subtraction with Regrouping (Borrowing) – Hands-On Lesson
Help students finally get subtraction with regrouping by trading tens, not magic borrowing. This complete lesson walks learners from concrete base-ten models to written algorithms, locking in the idea that when you regroup you add 10 to the place that needs more because you take 1 ten from the next place. Perfect for whole-group instruction, small groups, interventions, or sub plans. What’s Included Teacher Notes with objective, key insight, and step-by-step flow Anchor Chart: “What Really

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

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.

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
