Multiplication: Booklet 4

Multiplication: Booklet 4 – Working with Large Numbers and Decimals from Pattern Press is a hands-on math curriculum resource designed to help students develop a deep conceptual understanding of multiplication with large numbers and decimals through visual models, arrays, pattern exploration, and discovery-based learning.

This complete booklet set includes a 77-page Parent/Teacher Guide and a 77-page Student Workbook that guide students through advanced multiplication concepts using the Patterns in Arithmetic approach. Rather than simply memorizing multiplication procedures, students learn why multiplication works by exploring the distributive property, breaking numbers apart, recognizing patterns, and connecting visual models to standard algorithms.

Students investigate multiplication through arrays, arrow patterns, factors of ten, place value relationships, and multiple problem-solving strategies that strengthen long-term number sense and algebraic thinking. Decimal multiplication is introduced conceptually so students understand the structure behind the procedure, not just the steps.

The Parent/Teacher Guide includes teaching instructions, sample dialogues, games, lesson support, and the Answer Key. The Student Workbook includes worksheets and practice pages designed to reinforce understanding through active mathematical exploration.
