Notice many number sentences look alike, such as. This activity focuses on helping students learn to identify key terms that indicate multiplication or division.
Match the word problem with the correct number sentence. How many cars in all? Each pair of students will get about 40 colored tiles. Distribute a copy of the Multiply or Divide? Then demonstrate how to draw a picture of the model. Distribute at least 40 color tiles to each pair of students.
Students will practice using the contextual clues to translate and solve real-world problems. There are 3 kids. Ask students to complete this worksheet either in class or at home.
If students focus on division as being given the total amount and dividing it into equal groups, they will be ready for both types of division, even without understanding the subtle difference in how division can be presented.
Ask students to model this problem. Number 8 is this type of problem. When students solve real-world problems, they often struggle to determine what operation to use to solve the problem. Use the suggestions below to modify the lesson as needed.
Then we will solve the number sentences. If we help students read the multiplication as 3 groups of 6, they can use this meaning of multiplication to help differentiate between multiplication and division word problems.
Help students focus on multiplication as determining the total when there are a number of equal groups. The total was 14 bananas, it was divided into 2 equal groups, and the answer was the number of bananas in each group.
The Expansion section gives opportunities for students who are ready for a challenge beyond the requirements of the standard. A second way division presents itself is that the total is divided into groups of a specific size, and the goal is to decide how many groups can be created.
Each kid has 6 cars. For example, if there are 24 students and 48 cookies, how many cookies can each student have? During the school year, ask students to create real-world problems that involve multiplication and division. Be sure students still have access to the color tiles from the previous activity.
Instead, say we know there are 18 toy cars to be split equally among 3 kids. Ask students to draw the model on their practice worksheet. Activities are provided for students who may benefit from additional practice.
Although by the commutative property, the number sentence is not appropriate because there are not six groups of three cars. The Small Group section offers additional practice opportunities for students who could benefit from them.
The following is a summary of how you may want to discuss number 3, as this is the first division problem.The three subtraction sentences =8, =4, and =0 can be expressed as a single division sentence. The division sentence 12/4 = 3 means that, starting with the number 12, 4 can be subtracted 3 times to get zero.

Show Answers. What is division? Home > Printable Resources > Math Write sharing questions based on the division sentences shown below. The first one is done for you. Represent and solve problems involving multiplication and division. This is repeated subtraction. You subtract 4 repeatedly till you reach zero.
Each subtraction is a group of 4. How many groups? _____ How many times did you subtract? _____ That is the answer to the division problem 20 ÷ 4. Representing word problems are side without remainders, write a division problem?
Efficient strategy: number sentences are asked to represent and write out something about how did need in the problem? Riley wants to represent multi-step problems to problem.
Willis has a number sentence helps organize the multiplication, not able to. Students are asked to write number sentences to represent each problem and state the solution. Students will: differentiate between real-world multiplication and division problems using contextual clues.Download
