Show how many groups of 4 are in 20.
Division: Division is the process of splitting a number into equal groups. It's the opposite of multiplication and represents equal sharing or equal grouping.
- Identify the dividend (20) and divisor (4)
- Think: "How many times does 4 go into 20?"
- Use multiplication facts: 4 × 5 = 20
- Therefore, 20 ÷ 4 = 5
We need to find how many groups of 4 can be made from 20 items. This means sharing 20 equally among 4 groups.
Think of the multiplication fact that gives us 20 when multiplied by 4: 4 × 5 = 20
Since 4 × 5 = 20, then 20 ÷ 4 = 5
Check: 4 × 5 = 20 ✓
20 ÷ 4 = 5. There are 5 groups of 4 in 20.
• Division as inverse of multiplication: If a × b = c, then c ÷ a = b
• Equal sharing: Division means sharing equally among groups
• Fact families: 4 × 5 = 20, 5 × 4 = 20, 20 ÷ 4 = 5, 20 ÷ 5 = 4
Find how many groups of 5 are in 23 and what's left over.
Remainder: The amount left over when one number doesn't divide evenly into another. The remainder must always be smaller than the divisor.
5 × 4 = 20 (which is less than 23)
5 × 5 = 25 (which is greater than 23)
23 - 20 = 3
23 ÷ 5 = 4 remainder 3, or 4 R3
Check: (5 × 4) + 3 = 20 + 3 = 23 ✓
23 ÷ 5 = 4 R3. There are 4 groups of 5 in 23, with 3 left over.
• Division algorithm: Dividend = (Divisor × Quotient) + Remainder
• Remainder rule: Remainder must always be smaller than the divisor
• Verification: Check: (Divisor × Quotient) + Remainder = Original Number
Use your knowledge of multiplication tables to solve.
Division Facts: Basic division equations that correspond to multiplication facts, like 36 ÷ 6 = 6 because 6 × 6 = 36. These are the foundational building blocks for more complex division.
What number times 6 equals 36?
6 × 6 = 36
If 6 × 6 = 36, then 36 ÷ 6 = 6
Check: 6 × 6 = 36 ✓
This means 36 can be divided into 6 equal groups of 6 each.
36 ÷ 6 = 6. There are 6 groups of 6 in 36.
• Multiplication-Division relationship: Division is the inverse operation of multiplication
• Fact family: 6 × 6 = 36, 36 ÷ 6 = 6
• Memorization: Knowing multiplication tables helps solve division quickly

- Check: Verify by multiplying quotient by divisor
• Any number divided by 1 equals itself: n ÷ 1 = n
• Zero divided by any number equals zero: 0 ÷ n = 0
• Any number divided by itself equals 1: n ÷ n = 1 (where n ≠ 0)
• You cannot divide by zero: n ÷ 0 is undefined
• Division is not commutative: a ÷ b ≠ b ÷ a
• The remainder must always be smaller than the divisor

Questions & Answers
Question: Why is division so hard? I understand multiplication but division is confusing.
Answer: It's completely normal to find division harder than multiplication! Here's why and how to make it easier:
- Multiplication builds: 3 × 4 = 12 (combining groups)
- Division breaks down: 12 ÷ 4 = 3 (separating into groups)
- Think backwards: Division is multiplication in reverse
- Use what you know: If you know 4 × 3 = 12, then 12 ÷ 4 = 3
- Visualize: Draw pictures or use objects to see the groups
Practice with smaller numbers first (like 1-9) until you feel confident, then move to larger numbers!
Question: My child gets confused about which number goes where in division. How can I help them remember?
Answer: This is a very common issue! Here are helpful strategies:
- Use the phrase: "Dividend ÷ Divisor = Quotient" (the big number gets divided by the smaller number)
- Think sharing: "I have 15 cookies (dividend) to share among 3 friends (divisor)"
- Relate to multiplication: 15 ÷ 3 = ? because ? × 3 = 15
- Draw it out: Circle 15 items and draw 3 groups to see how many go in each
- Practice with words: "How many groups of 3 are in 15?"
Consistent practice with division examples will build confidence and understanding!
Question: What's the best way to introduce division facts examples to beginners?
Answer: Starting with examples is perfect! Here's the recommended sequence:
- Start with ÷1: Any number divided by 1 equals itself (easy confidence builder)
- Move to ÷2: Introduce as "sharing equally" or "splitting in half"
- Add ÷5: Connect to counting by 5s and money concepts
- Introduce ÷3: Use real objects like sharing 12 cookies among 3 friends
- Continue with ÷4: Think of it as "half of half" or 2 groups of 2
- Progress to ÷6, ÷7, ÷8: Build on previously learned facts
- End with ÷9: Use as a comprehensive review of all facts
Always connect to multiplication facts and use visual aids like arrays and grouping models!
Word Problem: A real-life situation that requires mathematical operations to solve.
Tom has 28 stickers total, needs to divide equally among 4 pages
28 ÷ 4 = ? (How many stickers per page?)
What number times 4 equals 28? 4 × 7 = 28
Each page will have 7 stickers
Check: 7 × 4 = 28 ✓
Each page will have 7 stickers.
• Equal sharing: Division means distributing equally
• Real-world context: Connect math to everyday situations

Division Pattern: A sequence where both dividend and divisor change proportionally, creating a consistent quotient sequence.
Dividends: 12, 18, 24 (increasing by 6)
Divisors: 2, 3, 4 (increasing by 1)
Quotients: 6, 6, 6 (constant)
Notice: 12 = 2×6, 18 = 3×6, 24 = 4×6
Each dividend is the divisor multiplied by 6
Next divisor: 5
Next dividend: 5 × 6 = 30
Next equation: 30 ÷ 5 = 6
5 × 6 = 30 ✓
30 ÷ 5 = 6. The pattern shows that when both dividend and divisor increase proportionally, the quotient remains constant.
• Pattern recognition: Look for relationships between numbers
• Proportional reasoning: When dividend and divisor change by same factor, quotient stays the same
• Verification: Always check with multiplication
