Use Repeated Subtraction to Divide
- Grade:
- 2
- Subject:
- Math
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.
Interpret Division as Groups of Objects
- Grade:
- 3
- Subject:
- Math
Interpret whole-number quotients of whole numbers, e.g., interpret 56 ÷ 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ÷ 8.
Solve Two-Step Word Problems with an Unknown (4 Operations)
- Grade:
- 3
- Subject:
- Math

Use Equal Sharing
- Grade:
- 3
- Subject:
- Math
This number sense lesson focuses on using equal sharing. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students identify the first letter of each person's name in the problem, and use the letters to make a tally table.

- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on converting between fractions and division problems. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students represent each fraction with the division symbol. Then, they solve the problem using multiplication facts or with long division, if necessary. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
Divide Multi-Digit Numbers By a One-Digit Number (with Remainders)
- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on solving division problems that have a remainder. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students identify the dividend and the divisor. Then, they solve for the division problem by following the basic steps of division (divide, multiply, subtract, and bring down) and writing in the remainder. Finally, students interpret the quotient and remainder. In addition to the lesson, there are eight pages of Independent Practice and review with questions modeled after current adaptive testing items.
Use the Relationship Between Multiplication & Division
- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on using the relationship between multiplication and division to check answers. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students identify the operation needed to check the answer. Then, they set up the multiplication or division problem and identify the numbers used to create the problem. Finally, students check the answer by solving the problem. In addition to the lesson, there are four pages of Independent Practice and review with questions modeled after current adaptive testing items.
Explain Multiplication Using Area Models
- Grade:
- 4
- Subject:
- Math
This number sense lesson focuses on using the relationship between multiplication and division to check answers. The lesson includes research-based strategies and questions that help prepare students for assessments. In this lesson, students write both factors in expanded form. Then, they set up the box model to perform multiplication in. Then, students find the answer by adding up all the box values. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.
Determine if a Number is Prime or Composite
- Grade:
- 4
- Subject:
- Math
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.
Find Quotients by Using the Relationship Between Division & Multiplication
- Grade:
- 5
- Subject:
- Math
This number and operations in base ten lesson teaches students how to use the relationship between division and multiplication to solve division problems. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students rewrite division problems as multiplication problems as a strategy to help find quotients. This lesson should be considered an initial first step to more complex division problems. By using multiples of 10 and 100, students are able to see the structure of what is going on without getting distracted by difficult calculation.
Divide Decimal Numbers
- Grade:
- 5
- Subject:
- Math
This number sense lesson focuses on dividing decimal numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students change the problem into long division form, if necessary, and move the decimal point in the divisor to change it to a whole number, if necessary. Then, move the decimal point in the dividend the same number of places. Finally, they divide the decimal numbers and put a decimal point in the quotient above the decimal point in the dividend. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items and eight flash cards on changing to long division form.
