Counting in tens

[Toocold]

My ds needs to learn to count in ten's, he can sort of count up to 40 and recognises numbers up to 20, is this a case of counting 1-10, 10-20, 20-30, 30-40, 40-50 and so on? He is is reception.

I know I can ask the school but it is quicker to ask here

I think it means being able to say 10, 20, 30, 40, 50, 60 to 100 and maybe back down from 100 to 0. (100, 90, 80).

If he's a bit older it might possibly mean to be able to start from 2 (or any other number) for eg. 2, 22, 32, 42, 52...... Hope this makes sense.

When ds says he is counting it tens e says 10,20,30,40,50,60,70,80,90,100....

Sorry, just seen he's in reception. Pretty sure it's just 10, 20, 30, 40 etc up to 100.

Great thank you!, I think he can do that, so is obviously not showing them at school

Yes in rec 10, 20, 30 etc

Start at 0 though! 0, 10, 20...

When you next see a thermometer you can show him that there are numbers below 0 too!
