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
