Multiplication Lesson Plan
This lesson combines the use of manipulatives with computer
technology to teach and reinforce the concept of multiplication.
Standards (NCTM Grades 3-5)
Number and Operations
Understand meanings of operations and how they relate to one another.
Compute fluently and make reasonable estimates
- Understand various meanings of multiplication and division;
- Understand the effects of multiplying and dividing whole numbers;
Students must be able to:
- Develop fluency with basic number combinations for multiplication and division
and use these combinations to mentally compute related problems, such as 30*50;
- Develop fluency in adding, subtracting, multiplying, and dividing whole
Have enough blocks for each student to have approximately 100 blocks.
The type of block is unimportant.
Students will need:
- perform basic mouse manipulations such as point,
click and drag.
- use a browser such as Netscape for experimenting with
- access to a browser.
- paper and pencil.
- Focus and Review
Review any pertinent vocabulary and tell the students that today they will be learning
how to multiply.
Students will understand and be able to perform 1 digit * 1 digit multiplication.
- Teacher Input
- Pass out blocks. (Any little cubic blocks you have access to)
- Instruct the students to place the blocks in 3 piles with 2 blocks in
Have students tell you how many total block they have arranged in piles.
- Repeat this with:
- 2 piles of 5
- 6 piles of 1
- 8 piles of 3
- Inform the students that what they are doing is multiplication.
- Place the students into pairs.
- Hand each pair of students 2 dice
- Guided Practice
- Demonstrate rolling the dice, writing down the numbers, and multiplying them
together by arranging piles of blocks and counting the blocks.
- Have the students do this for at least 10 rolls each.
- Walk around and monitor the students to ensure they are arranging the
- Demonstrate how to use the Arithmetic Four applet
- When first starting, have the students set the time limit to no time limit.
- Independent Practice
Extensions and Modifications
- Review what multiplication is. ( 6*7 = 6 piles of 7 blocks = 42)
- Pass out multiplication tables
and have the students look for patterns on it for homework.
- For those students who are not yet ready for multiplication this lesson can be
easily changed to an addition/subtraction lesson.
- Students who are more advanced can be challenged in several ways:
- You can have them set a shorter time limit for their turn.
- You can have them work on their division skills as well as their
- You can have them work with integers instead of just whole numbers.
