Standard 2: Develop an understanding of equality and multiplication and division.

Students are asked to solve a division problem using a calculator but without using the division key.

Type: Formative Assessment

Students are given multiplication and division equations within 100 and asked to find the missing numbers. The missing numbers are presented in all positions.

Type: Formative Assessment

Students are given multiplication equations with products within 50 and are asked to find missing numbers. The missing numbers are presented in all positions.

Type: Formative Assessment

Students are given division equations involving numbers within 50 and are asked to find missing numbers. The missing numbers are presented in all positions.

Type: Formative Assessment

Students are given multiplication and division equations within 50 and are asked to find missing numbers. The missing numbers are presented in all positions.

Type: Formative Assessment

Students consider a division fact that they are likely to know and are asked to turn it into a multiplication fact. If successful, they are asked to rewrite a basic division fact that they are not likely to know and which has a symbol for the unknown number.

Type: Formative Assessment

Students are given a word problem and asked to write an equation for the problem. Then the students are to select a multiplication equation that can also be used to solve the problem.

Type: Formative Assessment

Students are asked if the Commutative Property holds for division.

Type: Formative Assessment

Students are told of a visiting alien from a planet where division is not taught, and asked to rewrite four division problems as multiplication problems so the alien can do them. The students are also asked to explain why it might be easier to do the multiplication problems than the given division problem.

Type: Formative Assessment

Students will solve multiplication and division word problems by matching the word problem with a corresponding equation. Students will solve for the missing variable to find the answer to the problem. In this integrated lesson plan, students will read the problems to see how some students volunteer their time to organize items in a food drive.

This lesson is part 3 of a 3 lesson unit where students are learning about responsibilities citizens have to help the community with food drives.

In this Model Eliciting Activity, MEA, students will evaluate data and create a process for which Spin Blade would be the "best" for Mr. Brown's toy store. Data will include customer feedback, price, style, and revolutions per minute. Students will apply their understanding of division in problem-solving. They will write a letter explaining their procedure using grade-appropriate language conventions.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.

Type: Lesson Plan

This is an introductory lesson to explore the use of arrays to solve multiplication problems. Students build arrays and save the arrays in a class Multiplication Chart. They learn to use arrays to find products and factors, and by placing them in the Multiplication Chart, they learn how to read the chart. They learn how to write equations to represent situations that are modeled with arrays. An overall theme is the organization of the multiplication chart and how it includes arrays within.

Type: Lesson Plan

In this lesson, students will learn to solve division problems by relating them to multiplication facts. Practice materials focus on the 6's and 8's multiplication facts.

Type: Lesson Plan

This lesson will provide students with practical application activities to help them understand how division is simply solving a problem with an unknown factor. This activity includes opportunities for students to use fact families when identifying unknown factors and a tic-tac-toe game to provide whole group practice as well as to be used at a center, or for independent reinforcement of the skills.

Type: Lesson Plan

In this lesson students will use Cheerios to solve multiplication equations relating 3 whole numbers from word problems that include missing factors ranging from one through ten. Students will also argue the validity of multiplication equations that include missing factors and products with corresponding word problems.

Type: Perspectives Video: Teaching Idea

A problem for students to solve using students' understanding of the operations of addition, subtraction, multiplication, and division. The problem presents an opportunity for students to appreciate the value of approaching a solution in a systematic way using what they know about the structure of operations.
