trying my best Posted January 19, 2011 Share Posted January 19, 2011 I got 1A for my DS in our local discounted store. I only got him a text book thinking he is really ready for 1B (but maybe lacking some stuff from 1A). I thought 1A will last him a month or so just reviewing it. But today i set with him for the first time and he did a whole book in 1 hour! i was like :001_huh: He knows whats its all about and how to make numbers in a bond of 10 to do additions and subtractions and all that (regrouping to make it easier). He did half of it in his head. Will that be OK to start 1B with him? I have both textbook and writing book for 1B. Quote Link to comment Share on other sites More sharing options...
