We need help on place value!! My DD, 11, is working in MUS. We are on Delta lesson 15. It has become obvious that the previous lessons on place value are not totally mastered. She is right-brained, if that helps with any suggestions. She seems to learn something and so we move on just to find out later that we hadn’t really mastered it. I feel like this happens every year and that we really are not making any progress. She gets angry about using the blocks, today she was supposed to write a number that was given to her in words (60,000,006). She didn’t do it correctly, so I wrote lines for each place value to be filled in (_ _,_ _ _,_ _ _). That apparently was a “death sentence” to ask her to use that and put the numbers in their proper places. Before I used the lines, she wanted to write 6 million instead of 60 million. She had 6 hundred instead of 6. And, I don’t have millions, billions or trillions of blocks to build the numbers with. If I write a number and have her read it, she can read it to me. If I write a number and ask her to tell me what’s in the “millions” place, etc., she can do that. If I write a number and ask her what place the “5”, etc. is in, she can do that.
In the previous lesson, we were supposed to take a number (ex:65,470,123) and write it in place value notation (ex:60,000,000+5,000,000+400,000+70,000+100+20+3). This took several lessons of balking and not getting it and then suddenly she was doing it. Now, the current lesson we are supposed to break it apart even further (6×10,000,000+5×1,000,000+4×100,000+7×10,000+1×100+2×10+3×1). Today is our third lesson and it is the first time she has done that properly but when asked to make the number is still not putting things in their proper place value.
This isn’t a new concept. We’ve done this in previous books and I don’t remember it causing so much trouble in the past. Does she really not get place value? Does it have more to do with reading the word? Where can I get more place value practice? I really don’t know what to do!! Ideas? Help? Thanks
