These guides help teachers understand how federal assessments have evolved by showing in-depth analysis of assessment questions in math. Teachers will understand the new types of questions presented to students and how classroom instruction should be modified to prepare students for these questions.

This numbers and operations − fractions lesson covers how to express whole numbers as fractions. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will count the whole items in a picture, write the whole number, and then express that whole number as a fraction.

This number sense lesson focuses on determining if a number is prime or composite. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students read the number. Then, they determine if it is composite or prime by trying to divide by either 2, 3, 5, or 7. Finally, students justify their answer. In addition to the lesson, there are eight pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.

This number sense lesson focuses on reducing fractions. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students find the factors of the numerator and denominator. Then, they identify the greatest common factor (GCF) and write it down. Finally, they reduce the fraction by dividing the numerator and denominator by the GCF and interpreting the reduced fraction. In addition to the lesson, there are five pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items and 10 flashcards for reduced fractions.

This ratios and proportional relationships lesson covers how to compute unit rates (complex fraction ratios). The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students create an equivalent ratio table using given units and quantities. They identify the unit quantity, determine the multiplicative inverse which produces one, and then apply the multiplicative inverse to the other quantity. Finally, they interpret the unit rate.

This number system lesson covers how to determine the multiplicative inverse of a number. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students identify the given number, then determine its multiplicative inverse by switching the numerator and denominator. Finally, they interpret what it means, showing that a given number times it’s multiplicative inverse equals one.
