Lesson Overview
Lesson overview
Purpose: Build a clear understanding of division and learn reliable strategies for division facts, remainders, and long division.
Success criteria
Explain division as sharing equally (partitive) and as grouping (quotative).
Use the inverse relationship between multiplication and division to solve problems.
Use fact families to connect \(a\times b=c\) with \(c\div a=b\) and \(c\div b=a\).
Understand and interpret remainders using \(n = d\times q + r\).
Use efficient strategies for division facts (÷1, ÷2, ÷5, ÷10, halving, and checking with multiplication).
Divide larger numbers using estimate → divide → multiply → subtract → bring down (long division steps).
Key vocabulary
Dividend: the number being divided (in \(a\div b\), \(a\) is the dividend).
Divisor: the number you divide by (in \(a\div b\), \(b\) is the divisor).
Quotient: the result of division.
Remainder: what is left over when a division does not divide evenly.
Quick pre-check
Pre-check 1: Which expression means "share 12 among 3 equal groups"?
Hint: Division is used when you split into equal groups or ask how many groups fit.
Pre-check 2: Compute \(12\div 3\).
Hint: If \(3\times 4=12\), then \(12\div 3=4\).
Sharing & Grouping
Division as sharing and as grouping
Learning goal: Recognize two meanings of division and choose the correct model for a word problem.
Key idea
Division answers "How many in each group?" or "How many groups?" depending on the situation:
Sharing equally (partitive): Split \(n\) items into \(d\) equal groups. How many in each group? That is \(n\div d\).
Grouping (quotative): Make groups of size \(d\). How many groups fit into \(n\)? That is also \(n\div d\).
Worked example
Example: \(15\div 3\)
Sharing: 15 stickers shared into 3 equal groups gives 5 in each group. Grouping: How many groups of 3 fit in 15? There are 5 groups. So, \(15\div 3 = 5\).
Try it
Try it 1: "24 cookies are shared equally among 6 friends." What operation matches?
Hint: Sharing equally means divide the total by the number of groups.
Try it 2: Compute \(49\div 7\).
Hint: Use a related multiplication fact: \(7\times ? = 49\).
Summary
Division can mean sharing equally or counting how many groups fit.
Both models use the same notation \(n\div d\).
Inverse Relationship
Division and multiplication are inverses
Learning goal: Use multiplication to solve division problems and check answers quickly.
Key idea
Division "undoes" multiplication. If \(a\times b=c\), then: \(\,c\div a=b\) and \(\,c\div b=a\). This relationship builds division facts from multiplication facts.
Worked example
Example: \(56\div 8\)
Think: \(8\times ? = 56\). Since \(8\times 7 = 56\), the quotient is 7. Check: \(7\times 8 = 56\). Correct.
Try it
Try it 1: Compute \(48\div 8\).
Hint: Find the number that makes \(8\times ? = 48\).
Try it 2: If \(9\times 4 = 36\), which division sentence is true?
Hint: Fact families connect one multiplication fact to two division facts.
Summary
Use multiplication facts to find division quotients faster.
Always check with \(q\times d\) to confirm.
Facts & Strategies
Efficient strategies for division facts
Learning goal: Use patterns and mental strategies to divide quickly and accurately.
Key patterns
÷1: the quotient is the same number
÷10: move the decimal one place left (for base-10 numbers)
÷5: divide by 10, then double
÷2: halve
÷4: halve twice
÷8: halve three times
Check: \(q\times d = n\) (or \(q\times d + r = n\) with remainders)
Worked example
Example: \(72\div 9\)
Think: \(9\times ? = 72\). Since \(9\times 8 = 72\), the quotient is \(8\). Check: \(8\times 9 = 72\).
Try it
Try it 1: Compute \(81\div 9\).
Hint: Find \(?\) so that \(9\times ? = 81\).
Try it 2: Compute \(120\div 8\) using halving.
Hint: ÷8 means halve three times: \(120\to 60\to 30\to 15\).
Summary
Use patterns first (÷1, ÷2, ÷5, ÷10, powers of ten).
Use halving for ÷4 and ÷8, and multiplication to check results.
Remainders
Remainders and what they mean
Learning goal: Understand remainders and represent division with the equation \(n = d\times q + r\).
Key idea
When a number does not divide evenly, we can write: \(\,n = d\times q + r\), where \(0 \le r < d\). This shows the quotient \(q\) and the remainder \(r\).
Try it 1: What is the quotient in \(31\div 7\)? (quotient only)
Hint: Find the biggest multiple of 7 that is ≤ 31.
Try it 2: What is the remainder in \(31\div 7\)? (remainder only)
Hint: If \(7\times 4 = 28\), then \(31-28 = 3\).
Worked solution
Find the largest multiple of 7 that fits in 31: \(7\times 4=28\). Subtract: \(31-28=3\). So \(31\div 7 = 4\) remainder \(3\), and \(31 = 7\times 4 + 3\).
Summary
Remainders satisfy \(0 \le r < d\).
Use \(d\times q + r\) to check the division result.
Long Division
Long division step-by-step
Learning goal: Divide multi-digit numbers using estimate and repeated subtraction of multiples (the long division algorithm).
Key steps
Estimate: How many times does the divisor fit?
Multiply: Multiply the divisor by the estimate.
Subtract: Find what remains.
Bring down: Bring down the next digit and repeat.
Check: divisor × quotient + remainder = dividend.
Worked example
Example: \(84\div 6\)
Estimate: \(6\) goes into \(8\) one time. Multiply: \(1\times 6=6\). Subtract: \(8-6=2\). Bring down 4 → 24. Estimate: \(6\) goes into \(24\) four times. Multiply: \(4\times 6=24\). Subtract: \(24-24=0\). So \(84\div 6 = 14\).
Try it
Try it: Compute \(96\div 8\).
Hint: \(8\) goes into \(9\) once (remainder 1), bring down 6 to make 16, then \(16\div 8=2\). So the quotient is 12.
Worked solution
\(96\div 8\): \(8\) goes into \(9\) one time → remainder \(1\). Bring down 6 → 16. \(16\div 8 = 2\) remainder \(0\). So \(96\div 8 = 12\). Check: \(12\times 8 = 96\).
