DS will be 4 in Feb and really likes numbers. Like, his idea of heaven is watching Numberblocks on repeat and I often find him counting for fun. He is good at counting and knows some basic addition, also understands the concept of times tables and can do the 10x table accurately (obviously easy so not claiming he is some kind of genius!).
I am thinking about getting a numbers based toy for Xmas, esp something that would help him with addition. Bit stumped as to where to start though - any suggestions?
