Lessons tagged with "common-denominators"

Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.* For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.

This number and operations -- fractions lesson teaches students how to subtract fractions with like denominators. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will subtract fractions with like denominators. This lesson includes a variety of real-world examples. This lesson also covers reducing fractions.

This Common Core number and operations -- fractions lesson focuses on adding mixed numbers with like denominators. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students will read the problem aloud, identify the whole numbers and fractions, and write them as an addition problem. Then, they will combine the sum of both problems to determine the answer. Finally, they will reduce the fraction or regroup, if needed. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after the Common Core assessment items.

This number and operations--fractions lesson teaches students how to subtract fractions with unlike denominators. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students create equivalent fractions to subtract fractions with unlike denominators. Reducing the results is not addressed. This lesson focuses on unlike denominators that require both fractions to be changed.

This Algebra 1 lesson teaches students how to add rational expressions. The lesson includes research-based strategies and strategic questions that prepare students for assessments. Students will factor the polynomials in the denominator completely, if possible, and then create equivalent fractions by finding the common denominator by multiplying the numerator and denominator of each fraction by the same rational expression. Finally, they will add the rational expressions by combining like terms in the numerator, and simplifying if needed. In addition to the lesson, there is one page of Independent Practice and three pages of periodic review.
