The activity will be great for preschool or kindergarten math units. Your students will develop number sense, number recognition, and practice counting in ten frames.

## Building Teen Numbers

This digital back-to-school teen numbers activity is so versatile and easy to use. There are two different options for using this activity with your students. For each option, there are 9 slides, giving students a total of 18 slides.

For the first option, students will count on from 10, dragging the correct number of crayons into the bottom ten frame to match the addend shown. Then, they’ll type the teen number they made in the box to represent the sum.

Students are practicing number matching by looking at the addend and filling in the ten frame to match. This will help them learn more about putting 2 numbers together to make a teen number, thus, working on beginning addition skills.

For the second option, students will count on from 10, dragging the crayons into the bottom ten frame to reach the sum shown in the box. Then, they will fill in the missing addend in the missing addend box.

In this option, students are using their fine motor skills to drag and drop the crayons, working to solve for the missing addend. This helps them think critically as they count on.

## Differentiation Ideas

This teen number activity can be differentiated in many ways to work as a kindergarten math activity. Or use it in a first-grade classroom.

To offer more teacher guidance and support, you can complete this activity during whole group or small group instruction. Students can be leveled by skill to allow you to assign the slides they need and offer support at their level. You can even use this as a mini-lesson activity to reteach or review the concepts of teen numbers, counting on, and missing addends.

On the other hand, you may have students who don’t need as much support and are ready for a challenge. They can complete the activity independently using either the first option, second option, or both options. You can even mix up the slides allowing them to practice both options.

I like to encourage my students to point and count aloud, especially the first few times. This helps them practice one-to-one correspondence and tracking as they count on.

As you can see, this digital download has tons of benefits and uses for teaching math skills. It could be utilized in the classroom or for learning at home. This back-to-school activity will be great to get your students back in the swing of things or for continued teen number practice all year long!
