What Are Missing Factors?
Multiplication is like putting together pieces of a puzzle!
When one factor is missing in a multiplication problem, we can use what we know about numbers to find it. For example, if we know that 3 × ⬜ = 12, we're looking for the number that makes the equation true.
How to Find Missing Factors
1️⃣ Look at the equation: Identify the numbers you know and what's missing
2️⃣ Think of multiplication facts: What number times the known factor equals the product?
3️⃣ Check your answer: Multiply to see if it works!
Let's Practice Together!
Example 1: The Cookie Puzzle
Emma baked cookies and put them in 4 bags. Each bag has the same number of cookies. There are 24 cookies total. How many cookies are in each bag?
Equation: 4 × ⬜ = 24

Parent Tips 🌟
- Make it real: Use everyday objects like toys or snacks to create missing factor problems. "If we have 20 candies and want to give 4 to each friend, how many friends can we share with?"
- Fact families: Show how multiplication and division are connected. If 5 × 7 = 35, then 35 ÷ 7 = 5.
- Play factor games: Create flashcards with missing factors or play "I'm thinking of a number" games to reinforce the concept.
