Hi! I was hoping someone could give me ideas or point me to some good websites. The 5th grade teacher I co-teach math with wants me to have some ideas to work with place value. I’m a new teacher, so any help would be much appreciated. :) Thanks,
Aimee
Re: place value
I have used the concept of naming the commas to make place value easier. The first comma (on the right) is the thousands comma - then the millions comma then the billions comma. This also makes it easier to read large numbers such as 452,341,009. they can read the number four hundred fifty two million, three hundred forty one thousand, nine.
Re: place value
I have combined using different colors and using commas to signify the different “last names” of number fmilies, and I use non-white graph paper with faint lines. For example, all familys have three digits–hundreds, tens, ones—that are read like regular numbers (432, four-hundred thirty two) and all members of the same 3-digit family are the same color and share a last name (432,601,357: student decides green for millions, red for thousands, pencil color for hundreds or regular numbers). Underneath the digits written in color, copy the color-coded digits and the last name and comma written in the same color. This distinguishes differences while reinforcing similarities (432 MILLION,-green; 691 THOUSAND,-red; 357-regular pencil).
From there, I use all words but keep the color. My LD community college students then use colors as grouping symbols when translating words to symbols.
Good Luck!
I’ve seen teachers for 5th use a chart where there are columns with each being a place value. The center column is the decimal point with AND written in (since that is what you say) and the columns before and after are headed with hundreds, hundreths, etc.
Having the students fill in the chart while you verbally read them a number worked well for the students in her class. I was just there for the day subbing but I made a copy and have used it since then.
