Grade 4: Math
Start with a unit whose prerequisites fit. Work through the lessons, use the study guide to review, and try the new cases before continuing.
- Unit 1 · 4 lessons
Use Large Whole Numbers and Explain Algorithms
Read larger place values, round them, multiply, and divide with interpreted remainders.
Before you begin: Read three-digit numbers; multiply one-digit factors; regroup whole-number operations.
- Unit 2 · 4 lessons
Compare Multiplicatively and Investigate Factors
Distinguish times-as-many from more, find factors, classify primes, and explain patterns.
Before you begin: Multiply and divide within one hundred.
- Unit 3 · 4 lessons
Equivalent Parts for Fraction Reasoning
Use equivalent fractions to compare amounts and count joined or repeated parts.
Before you begin: Name fractions of equal parts of a whole. · Recognize 1/2 in equivalent models and multiply small whole numbers.
- Unit 4 · 4 lessons
Extend Fractions to Mixed Numbers and Decimals
Operate on mixed numbers and connect tenths and hundredths with decimal notation.
Before you begin: Use equivalent fractions and add or subtract like parts.
- Unit 5 · 4 lessons
Convert Measurements and Use Fractional Data
Convert larger to smaller units, calculate time, solve rectangle dimensions, and summarize line-plot measures.
Before you begin: Use area and perimeter; add like-denominator fractions.
- Unit 6 · 4 lessons
Measure and Combine Angles
Read ray turns, degree scales, adjacent angles, and unknown angle parts.
Before you begin: Recognize a right angle; add and subtract whole numbers.
