The first page of this site compares stem and leaf plots to other types of graphs and gives explanations. The second page gives good descriptions of how to create a back to back stem and leaf which is what you'll find on your unit assessment. Don't forget the key and title!

This is a good site for measurement practice because it allows kids to measure with a ruler similar to the one they'll have in their Benchmark envelopes.
This site is great for showing kids rulers with different measurement divisions. Note that in 5th grade their SLE is to the nearest 1/4 inch, but the smaller units would be a good challenge for students who are ready.
This site will allow you to create worksheets with 2 or 3 sets of data to combine. Note that in 5th grade students must list and explain, so they'll need to be able to do more than tell how many combinations can be created.
This site is great for practicing long division step by step. Click Welcome, 5th Grade, then scroll down for Dividerama. There's also a printalbe worksheet.
Practice units and measures.
Various interactive activities.
This site is customizable to allow for differentiated instruction.

Practice entering data to create circle graphs.
This game can be set to quiz kids from increments of one to 1/16 of an inch. To avoid confusion in future years, stress to kids that mixed measurments such as 2 and 1/4 are written as 2-1/4 but don't mean 2 minus 1/4.
This is a great game both to practice with part-to-part ratios and also to strengthen understanding of simplifying fractions. You can have students use the floating pen tool to circle objects in the unsiplified ratios and then write the two as equal fractions. If you add this, you'll also be teaching NO.3.5.5c.
This site will help review the creation of basic stem and leaf plots before you move on to more complex back to back plots.
This site allows kids to measure and create rectangle replacement windows for houses. In order to meet this SLE, they'll need to sketch the rectangles, record the dimensions, and find the perimeter and area.
This site is wonderful for creating and manipulating all types of graphs.
The 5th grade SLE requires that kids be able to draw and measure distance to the nearest cm and 1/4 inch.
This site has flash cards that test your knowledge of which units to use.
This site will let you practice with measurements on the reference sheet.
