Mastering Place Value to One Million
WALT: Understand place value up to 1,000,000 Year 5 Functional Skills Mathematics 60-minute lesson
WALT - We Are Learning To
Identify and understand place value of digits in numbers up to 1,000,000 Represent and interpret numbers in different forms including expanded notation Compare and order numbers up to 1,000,000 Round numbers to the nearest 10, 100, 1,000 and 10,000
Success Criteria - What Success Looks Like
I can explain the value of each digit in a given number up to one million I can write numbers in expanded form correctly I can compare two numbers and say which is larger or smaller I can round numbers to the nearest specified place value accurately
Starter Activity: Build Your Million
Use number cards 0-9 to create a 6-digit number Identify what each digit represents in your number Use the place value grid to check your understanding Challenge: Can you make the largest possible number?
Understanding Place Value Positions
Each position has a specific value: ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions The digit 5 means different things depending on its position Example: In 345,672 the 5 represents 5,000 (five thousands) Zero acts as a placeholder to keep other digits in correct positions
Expanded Form and Standard Form
{"left":"Standard Form: 345,672\nExpanded Form: 300,000 + 40,000 + 5,000 + 600 + 70 + 2\nStandard Form: 508,039","right":"Expanded Form: 500,000 + 8,000 + 30 + 9\nNotice how zeros create gaps in expanded form\nBoth forms represent the same number value"}
Comparing and Ordering Numbers
Compare these numbers: 234,567 and 234,576 Start from the left (highest place value) Find the first different digit The larger digit makes the larger number Practice ordering: 45,230 | 452,300 | 45,032
