1. Factors and Multiples

Workbook

• Factors, multiples, and factor pairs.

• Prime vs. Composite numbers.

• Area and side lengths of rectangles as factors.

• Building fluency with multiplication. 

2. Fraction Equivalence and Comparison

• Area as a foundation: Multiples are made up of Factors

• Factor Pairs within AREA 

• Multiples: Understanding that the area is a multiple of each of its side lengths 

• Prime & Composite Numbers: (prime has only two factors, composite has more). 

• Area & Factors: Using rectangles (area diagrams) to find all whole-number side lengths (factor pairs) for a given area (a multiple).

• Multiples: Understanding that the area is a multiple of its side lengths.

• Prime & Composite Numbers: Classifying numbers based on their number of factor pairs (one pair vs. multiple pairs). 

• Decimal Representation: Reading, writing, comparing, and ordering decimals to the hundredths, often on grids representing 1 whole.

• Place Value: Understanding the relationship between places (e.g., 1 ten-thousand is 10 thousands) and representing numbers beyond 1,000.

• Standard Algorithm: Adding and subtracting large whole numbers using the standard algorithm.

• Number Lines: Locating and comparing decimals and large numbers on number lines. 

• Multiplicative Comparison: Understanding and solving problems like "How many times as many?" or "times as many," using diagrams and equations.

• Measurement Conversion: Converting units within a system (e.g., meters to centimeters, liters to milliliters, kilograms to grams, pounds to ounces) by understanding their relationships.

• Problem Solving: Tackling one-step and multi-step word problems that combine multiplicative comparisons and measurement conversions.
