Title - Magic Numbers (Multiplication Webbing)
By - Christy Jones
Primary Subject - Math
Secondary Subjects -
Grade Level - 4-5
Objective: Students will apply knowledge of basic multiplication problems to find problems that equal the "magic number."
Materials:
Chalkboard
Scrap paper
Pencil
Procedure:
1. Draw a circle on the board. Draw four lines (about 6 inches) extending from the circle. Draw a rectangle at the end of each extension.
2. Write a number in the circle. This number is the magic number. Example : 6.
3. Ask students to copy the web onto a piece of scrap paper.
4. The students are to think of basic multiplication problems that equal the magic number (6) and fill in the rectangles on their scrap paper. (2x3, 3x2, 6x1, 1x6)
5. Go over the answers as a class.
6. Repeat activity and gradually increase the difficulty level.
Extension:
The teacher may add more rectangles to the web when more possible answers are available. For example: 24.
The teacher may rule out the replication of problems. For example, 2x3 and 3x2 only one of the problems will count in the rectangles.
The activity can be used as a game for speed.
Evaluation:
Did students successfully answer the problems that equal the magic number?
Did students pay attention and copy webs along with class?
This activity also works great with division!!
