Synopsis: This game looks at the basic idea of building a bridge of the proper length when you are given various segments that vary in size.

Synopsis: Though a title may make it sound like this is a site that only has rulers, it is anything but that. This site not only has games that look at showing your understanding of centimetres and millimetres, this site has games to show that you can read a scale, a thermometer, a clock, and more.

Synopsis: In this game, you can not only choose if you are measuring in centimetres or inches, but you can also choose if you will use whole numbers or bring decimals in (perhaps for your stronger students).

Synopsis: This site has some interactive activities that look at the measurement of weight, area, and length in both standard and non-standard units.

URL: https://phet.colorado.edu/en/simulations/masses-and-springs/about

Synopsis: This site has a simulator of springs that allows you to change the mass of the objects hanging on the spring or the spring constant (how tight or loose the spring is) to have students learn about stretching properties of objects. If you really want to go outside the curriculum, you can also change the gravity of planet where the simulation is taking place, or display the weight and spring tension as vectors. 

Note: When opening the app, you will likely want to select "Lab" as where you take this simulation.
