I have already borrowed the book from the library. After reading, I still get some enquiry that i would like u to help me.
1) when making "plus" equation e.g. 5 + 5 = 10, i need to hv 2 dots card of "5". In this case, how can i handle this? or i need to make one more card of "5". If making two cards of "5", is it necessary the dot position to be in the same? (I bought one set dot cards only) |
