If i may, .... the hardest thing to teach a baby is the math dot cards ...... if you are successful ..... then you can quickly move to numerals .... and you can start printing small numeral cards for them to play with and combine to numbers beyond 100 ...... in any case the purpose is to relate the dots or items to a human concept of defining this numbers and that is 1, 2, 3 ..... numerals .... once you do that the rest is easy ....
the hard part is to get them to see the dots ... and understand that that quantity of dots we humans using english calls it 10 ...., or using other language .... too .... LM can help you get the childs attention .... because its versatile enough to use other icons in place of red dots .... if your baby likes cats, or fruits ... you can use those ..... this will help babies to look at it and therefore build their interest in math .....
Also less headache getting the sticker dots or counting and printing the dots and printing it again when the baby tears it apart ...., it saves time choose the right icons he likes and get into action immediately ...., get it over in 6-9 mths and start doing written or printed equations ... or better still use a white board ....
