The students learn to solve the division table of 3.

Standards

CCSS.Math.Content.3.OA.B.5/6

Learning objective

Students will be able to solve the division table of 3.

Introduction

You ask student volunteers to drag the flags into the correct order and you ask what they notice. The correct answer is that they are making steps of three between each flag. Next you practice the table of 3 on the board with the students.

Instruction

First you discuss the importance of calculating division problems. Next you explain that with a division problem you have a certain amount in each group and that with the division table of 3 you are going to divide by 3 each time. For this you show an example of 9 chocolates, that are going to be divided evenly between 3 children. From here you can use the bar on the bottom right of the lesson to navigate through the lesson (visual, abstract, story) to discuss the learning goal in the order you want. Otherwise you continue with the pages in order and begin with the problems with visual support. Here you explain how you solve a division problem by telling how division problems work with images of lady bugs on a leaf, next you practice by dividing a number of rabbits into 3 cages. After this you show the images and the students must come up with the problem that matches each image. Then you show an image and ask a student volunteer to divide the dollars into the wallets and to divide the elephants into the 3 fields. After this you have the students make their own division problems using an image. Next you discuss the abstract problems. First you show what a division problem with 3 looks like when you divide the number evenly into 3 groups. Then you show the division problems with 3. Next the students practice more problems from the division table of 3. Then you walk through the steps of solving a story problem. The students can click on the speaker to hear the story.

Check whether the students can solve the division table of 3 by asking them the following questions:
- What does the problem 6 ÷ 3 mean? Can you give an example?
- Can you flip the numbers in a division problem?

Quiz

The students test their understanding of solving the division table of 3 through ten exercises. For some of the exercises they have visual support, others are abstract problems and other exercises are in the form of a story problem.

Closing

You have the students solve another problem with visual support, and after this another abstract problem and then they answer another story problem. Finally you can also play tag. A student says the name of another student and a problem from the division table of 3. The student whose name has been called must give the answer before they are tagged, otherwise they are "it".
