This number sense lesson focuses on subtracting numbers (two digits long). The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students determine if regrouping is needed. Then, they subtract digits in the ones place, and in the tens place. Finally, students read the problem and sum aloud. In addition to the lesson, there are "lining up subtraction" flashcards along with seven pages of Independent Practice and review with questions modeled after current adaptive testing items.

This operations and algebraic thinking lesson covers how to memorize subtraction facts. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will practice the subtraction facts of numbers 2 through 10 by a combination of reading aloud and writing each fact many times in horizontal and vertical formats.

This number sense lesson focuses on using repeated subtraction to do division. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students write down the number from the division problem. Then, they subtract the numbers to find out how much is remaining, and repeat the subtraction until there is nothing remaining. Finally, students count the number of times they subtracted and write it in the answer space of the division problem, and read the original division problem aloud. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.

This lesson covers how to subtract numbers with decomposing. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will line up the numbers by place value of their digits, subtract the digits in each place value, decompose the number (if needed), and then interpret the difference. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the assessment items.

Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

This number and operations in base ten lesson teaches students how to subtract multi-digit numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students will extend their knowledge of multi-digit subtraction by adding numbers up to the hundred thousands. Students will apply the standard addition algorithm with a focus on correctly lining up the numbers by place value and decomposing digits correctly. This lesson also contains real-world examples for students to practice with.

This number sense lesson focuses on using pictures to subtract fractions. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students represent the difference of the fractions by shading the number of equal parts. Then, they subtract fractions by using the pictures (keeping the common denominator and finding the numerator by subtracting the number of equal parts). In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.

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 number sense lesson focuses on subtracting decimal numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students identify the numbers that are being subtracted, if needed. Then, they line up the decimal numbers by place value, making sure the decimal points line up. Finally, they subtract, line up the decimal point in the difference, and interpret the difference. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing 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 and functions lesson focuses on using the order of operations. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students determine which operation to perform first (using PEMDAS) and repeat the order of operations until no more can be performed. Then, they compute the final value. In addition to the lesson, there are thirteen pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.

This expressions and equations lesson teaches students how to solve one-step equations. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students solve one-step equations with a variety of operations. The focus of this lesson is to solve one-step equations related to word problems.

This algebra and functions lesson focuses on using the distributive property in expressions with variables. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students identify the factor and then multiply the factor outside the parentheses to each value inside the parentheses. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items and six flash cards.

This algebra and functions lesson focuses on using a variable to write an algebraic expression. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students read the problem, identifying the unknown amount, the given number or known amount, and the operation (using clue words or actions such as sum, difference, product, or quotient). Then, they write the algebraic expression. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.

This number system lesson teaches students how to add and subtract multi-digit decimals. The lesson includes research-based strategies and strategic questions that prepare students for assessments.
