Product Description
This is only a 3 slide presentation. However, there is a lot of value in this PowerPoint activity. The students are all given 8 fractions bars. To make the bars I would used a paper cutter and cut strips 2 1/8 inches wide by 11 inches long. Make extra because there will be mistakes made in folding! I am sure with some experimentation you can figure how to fold the bars to make the necessary divisions. However, the 1/5 are the hardest. If you hold the paper horizontal (the 11 inch side parallel to the table), take the top left corner and fold it down to make a right triangle. The base will be about 2 1/4 inches. To be exact you need 2 2/5, but we are close enough for fraction bars. Now, keep folding that right triangle to the right until you have 5 of them. Then progress through the PowerPoint presentation with the 1/2, 1/3, 1/4, 1/5, 1/6, 1/8, 1/9 and 1/10. I did this activity for about 10 years. If you three hole punch the fraction bars before handing them out the students can then keep them in their notebooks. Have fun.
