Lesson COG 52
Task: Do basic multiplication.
Prerequisites: COG 23, COG 35, COG 41, COG 43, S&L 7
Concept: This task is typically learned through rote memorization. It is important, however, to also demonstrate the concept of multiplication in physical or concrete terms as well. Although not listed as a prerequisite, some walking ability is required. Modifications such as creating a game board-type concept may be needed for students with walking difficulties. In this lesson, the number 0 is avoided due to the conceptually abstract nature of this type of problem, but it could be added if desired.
Behavioral Objective: When presented with a multiplication problem of two single digits, the student will respond with the correct answer to a 90% accuracy level for 20 trials.
Materials: Make flash cards for each of the possible multiplication problems for .1 single-digit numbers 1 through 9 (problem on front and answer on back). Make "foot"-shaped designs from poster board that have the numbers 1 though 81 on them. Also needed are paper, color stickers, and markers.
Task Analysis:
1. Lay the foot shapes in numerical order on the floor with a spacing no that the student can step from one number to the next. (Note. These may have to be temporarily taped down.) Have the student begin at the number 1 and have the student count each step until he or she reaches the number 10. Explain how this action represents the multiplication of numbers by 1. Repeat this process for other examples.
2. Place some form of marker, such as a red piece of cloth, on one leg of the student. Start at a place before the number 1, begin with the unmarked leg on the number 1, and have the student draw a mark on a piece of paper each time the marked leg is used. Explain that this process is called multiplying by twos. On a piece of paper, draw the number 2, a multiplication symbol, the number 10, and the equals sign. When the student has made 10 marks on the paper, ask him or her to tell you the number on which he or she is now standing. Show the resulting complete multiplication problem. Continue this process for other even two-digit numbers.
3. Modify Step 2, placing color stickers by every third footprint, and demonstrate the "threes" concept.
4. Continue Step 3 for the numbers 4 through 9.
5. Using the flash cards, begin with the ones, then twos, and so forth. Keep repeating the process, focusing on just one number series at a time.
6. Begin introducing the flash cards in a random manner. Continue until the objective is met.
