Time

30 minutes

Approach

Hands-on exploration, guided practice, and interactive games.

Materials

Whiteboard or projector, Slide Deck: Multiply Your Fun!, Warm Up: Fast Facts, Worksheet: Multiplication Maze, and Cool Down: One-Minute Multiply

Prep

Review Materials

10 minutes

Step 1

Warm-Up: Fast Facts (5 minutes)

5 minutes

  • Begin with the Warm Up: Fast Facts activity. Have students quickly answer the multiplication problems.
  • Briefly review answers as a class, highlighting any common areas of confusion.

Step 2

Introduction: What is Multiplication? (7 minutes)

7 minutes

  • Use the Slide Deck: Multiply Your Fun! to introduce multiplication as repeated addition.
  • Go through slides 1-3, explaining arrays and groups to visualize multiplication.
  • Ask students for examples of multiplication in everyday life.

Step 3

Guided Practice: Array Adventure (8 minutes)

8 minutes

  • Continue with the Slide Deck: Multiply Your Fun! on slides 4-6.
  • Work through a few examples of creating arrays together on the board.
  • Have students try drawing their own arrays for simple multiplication problems in their notebooks or on mini whiteboards.

Step 4

Independent Practice: Multiplication Maze (7 minutes)

7 minutes

  • Distribute the Worksheet: Multiplication Maze.
  • Explain the instructions: students solve multiplication problems to navigate through a maze.
  • Circulate to provide support and answer questions.

Step 5

Cool-Down: One-Minute Multiply (3 minutes)

3 minutes

  • Conclude with the Cool Down: One-Minute Multiply.
  • Have students quickly solve the problems to assess their understanding of basic facts.

Slide Deck

Multiply Your Fun!

Let's discover the magic of multiplication!

Welcome students and introduce the topic of multiplication. Emphasize that it's a way to quickly count groups. Ask students if they have heard of multiplication before.

What is Multiplication?

Multiplication is a faster way to do repeated addition!

Instead of 2 + 2 + 2 = 6, we can say 3 x 2 = 6.

Explain that multiplication is essentially repeated addition. Use a simple example to illustrate this concept (e.g., 3 groups of 2 is 2+2+2).

Seeing Multiplication: Arrays

Arrays help us see multiplication! They are objects arranged in rows and columns.

Think of a chocolate bar or an egg carton!

Introduce arrays as a visual tool for understanding multiplication. Explain that arrays are objects arranged in rows and columns.

Let's Build an Array!

How many rows?
How many columns?
Total = rows x columns

Show an example of an array and relate it to a multiplication problem. Walk through how to count the rows and columns to get the product.

Your Turn! What's the Multiplication?

Look at the array. What multiplication problem does it show?

Present a new array and ask students to determine the multiplication problem it represents. Encourage them to explain their reasoning.

Important Words: Factors and Product

The numbers you multiply are called factors.

The answer to a multiplication problem is called the product.

Introduce the terms 'factors' and 'product'. Emphasize that these are the special names for the numbers we multiply and the answer we get.

Answer Key

Multiplication Answer Key

Fast Facts Warm-Up

  1. 3 x 4 = 12
    • Thought Process: 3 groups of 4, or 4 + 4 + 4 = 12.
  2. 2 x 7 = 14
    • Thought Process: 2 groups of 7, or 7 + 7 = 14.
  3. 5 x 3 = 15
    • Thought Process: 5 groups of 3, or 3 + 3 + 3 + 3 + 3 = 15.
  4. 6 x 2 = 12
    • Thought Process: 6 groups of 2, or 2 + 2 + 2 + 2 + 2 + 2 = 12.
  5. 4 x 5 = 20
    • Thought Process: 4 groups of 5, or 5 + 5 + 5 + 5 = 20.
