Where is your 5 year old?

Liebs was adding 2-digit numbers easily around his 5th birthday and expressing his ideas about maths. These, at that time, included the basics of algebra.

Encourage it. The world needs people who are confident in their maths.

The IXL website shows what skills are supposed to be achieved in each year if you are curious. Addition to 10 appears to be a Year 1 skill, so he is ahead of what is expected. I always love hearing about kids being great at maths - keep being proud

My DS is also in pre-primary (yep same as Kindy in NSW) and in his school they will know counting to 100 (and over) 2 times tables to 20 (DS taught himself past 100 just by playing basketball!), 5 times tables to 50, basic addition (DS does number sentences). He can also do it all in his head, which is way better than I can do!

Everyone in his class are at different stages though. I do think my DS is also a genius! Probably because he rocks at maths and I was always so bad at it!

Sounds like you have every reason to think he's totally amazing

DS1 will be 6 next month.

He can count to 100, skip count (2,4,6 or 5,10,15 etc), basic addition and subtraction, read the time pretty accurately.

His spelling is awesome, he's now spelling words like scream, said, puppy, kitten etc, no more cat, hat for him lol

Sounds like your DS is doing really, really well!
