My kids love a scoot activity!! For this scoot, students will identify the shaded and unshaded fraction of each picture. In 3rd grade, we're required to do so much more with fractions, but some of my students still struggle to simply identify fractions. This activity is also a good way to introduce how you can add the 2 parts to make the whole.
You can use it as a scoot activity in your classroom or in the hall... Use it as a math center or a "solve the room" center.
