Making Numbers Beyond 10,000
Year 3 Mathematics Place Value Structures Lesson 3 of 8
What We'll Learn Today
Make and represent numbers beyond 10,000 Use place value language correctly Explore proportional and non-proportional materials Play games to practice our skills
Proportional Materials Review
Base 10 blocks show the real size of numbers 1 ten block = 10 ones 1 hundred block = 10 tens = 100 ones We can see and feel the quantity
Can you order these numbers?
3,247 1,089 5,634 2,156 4,891
What About Really Big Numbers?
Numbers beyond 10,000 are too big for blocks We need a different way to show them Non-proportional materials help us Same size pieces can represent different values
Non-Proportional Materials
Money is non-proportional A $50 note isn't 50 times bigger than a $1 coin We agree on what each piece represents Place value circles work the same way
Meet the Place Value Circles!
Blue circles = ones Purple circles = tens Orange circles = hundreds Red circles = thousands Green circles = ten thousands
Guided Practice
Work with your partner Make these numbers with circles: 3, 105, 831, 1,009, 3,421, 35,823 Explain why you chose each circle
Spin and Represent Game
Take turns spinning the spinner Collect the matching place value circle Place it in the correct column Write your total Aim for the largest number!
What Did We Learn?
Numbers beyond 10,000 need special representation Non-proportional materials help with big numbers Place value circles show position and value We can make and represent any large number
