After introducing your class to what a ten frame is and how it can be used give each student their own ten frame to work with. Ten frames are all about understanding the value of numbers. Ten frames help your students visualize equations and give them an opportunity to practice subitizing. The reason we teach our students all of these addition strategies is the desire to develop a more robust number sense. Keep in mind, skip counting leads students right into multiplication. Don’t forget to model skip counting tally marks by 5s. Paper and pencil work too, but it’s always fun to mix things up and it will keep your students engaged while learning this important skill.

Let’s start with a quick overview of the addition strategies that are introduced in kindergarten and first grade. This post covers the top tips and tricks for teaching the strategies 1st & 2nd-grade students learn to use when solving addition equations. ![]() These strategies help develop fluency and a deeper number sense.
