Lesson Plan
You can take students outdoors for this lesson, or you can do it indoors. The lesson demonstrates in a very visual and active way the concept of division with remainders.
Planning for the Lesson
To start, count the number of students present in your class. Can that number be divided by 3, 4, or 5? Draw chalk circles on the pavement outside, or use yarn to form large circles on the floor indoors.
If you have 17, 19, 22, or 26 students present, you might want to include yourself in the activity so that you can have a number of people that is divisible by 3, 4, or 5.
Now That Youre Ready
Now that you have the chalk or yarn circles set, invite students to move about and stand in one of the circles. When each student has settled into a circle, ask them to count the number of students in their circle and in the others. (Some circles might have more people than others in them.)
Then challenge students to move about so that each circle ends up having an equal number of students in it. Write on the white/blackboard the math problems that this exercise illustrates. For example, if you have 25 students and five circles,
25 students divided among six circles result in 4 students to a circle with one student left outContinue creating different numbers of circles from chalk or yarn. Based on this sample class of 25 students, you might
25 ÷ 6 = 4 remainder 1 (or 4 r1)
Reinforce the Lesson
Next, you might create a worksheet that looks something like the table below. Students will employ the same skills they used to group themselves as they divide the Number of Students among the circles provided.
Note: On your worksheet, the circles will be larger. Students will be able to draw equal numbers of dots in each circle, just as the divided themselves equally among the yarn/chalk circles you created.For each number of students in the first column, students can draw dots in the circles to represent how that number will be divided equally among the circles and how many of that number of students (dots) will be left out (remainder). Answers appear in red type.
Extend the Lesson
