Although I have a printable set of color-coded fraction/decimal strips that is a best selling item in my store, I find that having students create their own set by cutting, measuring, and folding, assists my students in understanding fractions. I also know that they need meaningful reasons to measure with a ruler.
I keep the printable version for my math stations and have students keep a copy in their notebooks.
I start by cutting a set of 3 X 12 inch strips for each student. (Some teachers want a laminator at home. I want my own paper cutter.)
I reserve one strip to represent the whole. We measure its length -- 12 inches.
Next we fold and cut the color we are using to represent half. I have them measure the half -- 6 inches. I ask what is 2X6? Notice that I have cut one and left the other uncut. I find that some students need fraction bars that they can manipulate.Next we fold, cut, and measure the color representing thirds. Each piece should be 4 inches. What is 3X4?
Then we fold, cut, and measure fourths. What is 4X3?
I do take time to have them write the words and numbers on each part. As we use these to solve problems, it helps to have both.
Next week I will continue with sixths, eighths, and twelfths.
