**Place Value**Writing 5-digit numbers and understanding the value of each digit Objectives Day 1 Understand place value in 5-digit numbers. Day 2 Add and subtract 1, 10, 100, 1000, 10,000. Day 3 Place 5-digit numbers on a line. Order and compare 5-digit numbers. Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Starters Day 1 Place value in 4-digit numbers (pre-requisite skills) Day 2 Count on/back in 10s from 3-digit numbers (pre-requisite skills) Day 3 Pairs to 100 (simmering skills) Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Starter Place value in 4-digit numbers Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Starter • Count on/back in 10s from 3-digit numbers Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Starter Pairs to 100 Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Objectives Day 1 Understand place value in 5-digit numbers. Year 5**Day 1: Understand place value in 5-digit numbers.**23,456 The comma helps us to read the number; the digits before the comma tell us how many 1000s there are. I am going to read a number. Write the number on your whiteboard. Make sure the comma doesn’t look like a decimal point! 43,2611 In this number, the 4 tells us how many ten thousands, and then the 3 tell us how many one thousands. Year 5**Day 1: Understand place value in 5-digit numbers.**• Write the 5-digit number these place value cards make.

Year 5**Day 1: Understand place value in 5-digit numbers.**1 43,561 40,561 Write 43,561. Subtract 3000. Which digit will change? Subtract 61. Add 4. Add 210. 40,061 Now subtract 500. 40,000 40,004 40,214 Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Objectives Day 2 Add and subtract 1, 10, 100, 1000, 10,000. Year 5**Day 2: Add and subtract 1, 10, 100, 1000, 10,000.**45,462 1 45,463 45,472 What number is 1 more? Write it. 100 more? 1000 more? 10,000 more? 10 more? 45,562 46,462 55,462 Year 5**Day 2: Add and subtract 1, 10, 100, 1000, 10,000.**36,478 1 36,477 36,468 What number is 1 less? Write it. 100 less? 1000 less? 10,000 less? 10 less? 36,378 35,478 26,478 Year 5**Day 2: Add and subtract 1, 10, 100, 1000, 10,000.**• How can we make the third digit change to 4? • What do we need to subtract? • I am going to enter 30,567 into a calculator. • We will add or subtract multiples of 10,000, 1000, 100, 10 and 1 to make all the digits the same (4), • so the new number will be 44,444. • How can we make the first digit change to 4? • What do we need to add? • How can we make the fourth digit change to 4? What do we need to subtract? • How can we make the last digit change to 4? What do we need to subtract? • How can we make the second digit change to 4? What do we need to add? 44,444 30,567 Year 5**Challenge**Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Objectives Day 3 Place 5-digit numbers on a line. Order and compare 5-digit numbers. Year 5**Day 3: Place 5-digit numbers on a line; Order and compare**5-digit numbers. Where shall we put this digit to make the largest 5-digit number we can? Where do the three numbers belong on this landmarked line? , 3 9 Use these digits to write largest and the smallest possible numbers. 2 5 1 Year 5**Day 3: Place 5-digit numbers on a line; Order and compare**5-digit numbers. Where shall we put this digit to make the largest 5-digit number we can? Where do the three numbers belong on this landmarked line? , 8 4 Use these digits to write largest and the smallest possible numbers. 7 2 5 Year 5**Place Value**Writing 5-digit numbers and understanding the value of each digit Well Done! You’ve completed this unit. Objectives Day 1 Understand place value in 5-digit numbers. Day 2 Add and subtract 1, 10, 100, 1000, 10,000. Day 3 Place 5-digit numbers on a line. Order and compare 5-digit numbers. Year 5**Problem solving and reasoning questions**Sketch a line 0-100,000 Teacher marks a mystery number (e.g. 5000). What number have I marked? Children ask question to guess. Repeat. Adding 1, 10 or 100 each go. How many goes to turn 98,089 into 99,999? Year 5**Problem solving and reasoning answers**Sketch a line 0-100,000. Teacher marks a mystery number (e.g. 5000). What number have I marked? Children ask question to guess. Repeat. What strategies do children use to identify the numbers marked? e.g. locating 50,000 as halfway along the line and other significant markers such as 25,000 and 75,000. 5000 is relatively close to 0, the equivalent of 5 on a 0-100 line. Do children make that connection? Note that although in earlier years children may have completed a similar exercise with numbers to 1000, some may find the larger numbers intimidating so ensure lots of practice correctly reading and writing 5-digit numbers Adding 1, 10 or 100 each go. How many goes to turn 98,089 into 99,999? 20 Quickest will be to add 100s, then a final 10, the sequence is: 98,089 98,189 98,289 98,389 98,489 98,589 98,689 98,789 Year 5
