Dahliarw Posted December 2, 2011 Share Posted December 2, 2011 My ds is almost 7. He totally gets place value with manipulatives (i.e. thousands, hundreds, tens, ones and exchanging them like 10 ones for a 10 bar, 10 hundreds for a thousands cube, etc). What he is having trouble with is place value when he sees a number on paper. So if he sees 5621 he'll pull out one thousand cube, two hundreds, etc. I've explained working left to right and the largest number is always on the left. Anyone have any ideas for how to help reinforce this for him? An online game would probably be his preference, but I'm up for activities or worksheets or whatever it takes. I think a couple of extra lessons would cement this for him. Thanks! Quote Link to comment Share on other sites More sharing options...
boscopup Posted December 2, 2011 Share Posted December 2, 2011 Have you broken the numbers into expanded form? eg, 5621 = 5000 + 600 + 20 + 1 Quote Link to comment Share on other sites More sharing options...
Dahliarw Posted December 2, 2011 Author Share Posted December 2, 2011 Yeah, we do that using the number cards. Quote Link to comment Share on other sites More sharing options...
Kuovonne Posted December 2, 2011 Share Posted December 2, 2011 Have you tried overlapping place value cards, like these? Quote Link to comment Share on other sites More sharing options...
GingerPoppy Posted December 2, 2011 Share Posted December 2, 2011 Can he read the number aloud? If he sees 5621, does he know how to say it? If yes, then remind him to "listen to himself" when he says the number slowly--he will *hear* that he is saying five thousand, so he should pull out 5 of the thousand cubes, etc. If he can't say the numbers, I would suggest drawing, together, on a big piece of paper, a simplified place value chart. Make it big, colourful, and illustrated. When you draw, start with the ones column. Take a highlighter in a colour of your choice and draw a big column. Get him to notice that you're starting on the right or "far" side of the paper. Illustrate it with a character that you can call Mr. Ones. Leave a spot at the bottom of the column where you can place digits, which can simply be numbers written on squares. Then move on to the tens column. Choose a different highlighter and colour the whole column. Get your son to notice that you are moving across the page in the opposite direction to reading a word. Draw a character, and name it Mrs. Tens. Move on to the hundreds and the thousands this way, naming them perhaps Dr. Hundreds and Sir Thousands. Get your son involved in the illustrating. Then have him place digits into the various columns and tell you how much they are worth. By actively creating the chart with you, and having the added visuals of the colours and characters, he is more likely to remember the order. When he sees a number all by itself, remind him to visualize it fitting into the columns you created. Quote Link to comment Share on other sites More sharing options...
Dahliarw Posted December 2, 2011 Author Share Posted December 2, 2011 We do have those cards (or similar ones). I like the idea of reading aloud and illustrating. I'll work on that. I don't think it'll take much for him to "get" it, I just wasn't sure how to teach it differently. Thank you! Quote Link to comment Share on other sites More sharing options...
Free Posted December 2, 2011 Share Posted December 2, 2011 Have you tried writing the numbers in the Hundreds Tens Units columns? Something like this and this? Quote Link to comment Share on other sites More sharing options...
Dahliarw Posted December 2, 2011 Author Share Posted December 2, 2011 Have you tried writing the numbers in the Hundreds Tens Units columns? Something like this and this? No, another idea to try, thank you! I'm not worried about him learning carrying on paper yet (we do it with manipulatives), but simple problems like that would help. :) Quote Link to comment Share on other sites More sharing options...
rocketgirl Posted December 2, 2011 Share Posted December 2, 2011 Math U See's Decimal Street has been invaluable to us. Both for our child who had to go back and relearn it that way and for our children who began with it. Quote Link to comment Share on other sites More sharing options...
Dahliarw Posted December 2, 2011 Author Share Posted December 2, 2011 Thank you! I will look into that. Quote Link to comment Share on other sites More sharing options...
KristenR Posted December 2, 2011 Share Posted December 2, 2011 I don't know what you call this pouch thing...but we got ours as a handme down from another homeschooling family. Here is a picture of it- we love it and use it for numerous games and activities. Quote Link to comment Share on other sites More sharing options...

Also, it is really easy to make without have to invest in MUS. Quote Link to comment Share on other sites More sharing options...
Beth in SW WA Posted December 2, 2011 Share Posted December 2, 2011 We used RS math manips, place value cards & base ten blocks. We would "build" numbers with these various items. We also used MM blue Place Value 1, 2, 3. It worked. :) Quote Link to comment Share on other sites More sharing options...
