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!

Problem solving and reasoning questionsSketch a line 0-100,000Teacher 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?

Problem solving and reasoning answersSketch 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?

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
