Super Subitizing!

Subitizing is a critical component in developing number sense because it builds a strong foundation in future math skills such as decomposition and composition of quantities. It is the ability to view a set of objects and determine the amount without counting. For example, an adult uses subitizing when determining a number on a six sided dice automatically without counting. Check out the resources below that will help you incorporate subitizing activities into your daily classroom routine!

    Throughout the day, you can use dot cards to practice your students' subitizing skills. This is a FREE resource where you can find printable dot cards for your classroom. I laminated a set for myself and attached them to a ring. This is an EXCELLENT transition activity I use daily while we are in line waiting to go to specials or lunch. I show a card to each student and they have to quickly identify the quantity and tell me how they knew what the amount was without counting.

    After introducing subitizing to your class, you can use this AWESOME activity that requires virtually no material preparations! Students will have a blast identifying different quantities on dominoes and matching them to a corresponding written number. I love how it exposes students to a variety of dot patterns for the same number.

    Technology can be used to practice subitizing as well. You can project these digital dot cards to the class and have students quickly identify the amount.

    These six songs/videos are a FUN way to incorporate subitizing into your daily brain breaks. Have your students stand up and move around or march in place while practicing their super subitizing skills!
