Dividing Two-Digit Numbers With Confidence
Year 3-5 Mathematics Building Skills Step by Step WALT: Understand division as equal grouping
What is Division?
Division is the opposite of multiplication It means sharing things equally into groups We can use counters, drawings, and number facts WALT: Understand division as equal grouping
Let's Practice: 24 ÷ 3
Use counters to make groups Draw circles to show your groups Count how many groups you made Check: 3 × ? = 24
Division Strategies We Know
Skip counting backwards Using multiplication facts Making equal groups with objects Drawing pictures to show division WALT: Recall division facts for 2s, 3s, 5s, 10s
Guided Practice Problems
{"left":"36 ÷ 4 = ?\n48 ÷ 6 = ?\n30 ÷ 5 = ?","right":"How many groups can you make?\nAre all groups equal?\nWhat multiplication fact helps?"}
Year 5 Extension: Bigger Numbers!
We can divide larger numbers too! 68 ÷ 2 = ? Let's break it down 81 ÷ 3 = ? Use what we know WALT: Apply strategies for larger dividends
Strategy 1: Partitioning
68 ÷ 2 = ? Break 68 into 60 + 8 60 ÷ 2 = 30 8 ÷ 2 = 4 30 + 4 = 34
Strategy 2: Repeated Subtraction
81 ÷ 3 = ? 81 - 30 = 51 (subtract 10 groups of 3) 51 - 30 = 21 (subtract 10 more groups) 21 - 21 = 0 (subtract 7 groups of 3) 10 + 10 + 7 = 27 groups
Your Turn to Practice!
Try these problems using any strategy: 72 ÷ 3 = ? 84 ÷ 4 = ? Which strategy works best for you?
Reflection and Next Steps
Division is sharing into equal groups We can use grouping, partitioning, or repeated subtraction Check answers using multiplication Practice makes us more confident! WALT: Communicate our reasoning clearly
