Tens Frames are great graphic organizers to teach children complements of 5 and 10. They use these to practice what’s missing from a set to make it complete. As NCTM points out, ” The ten frame uses the concept of benchmark numbers (5 and 10) and helps students develop visual images for each number. For example, this device makes it easy to see that 6 is 1 more than 5 and that 6 is 4 less than 10.”
There are some great ten frame resources on the web. See these websites for ideas and manipulatives.
