3rd Grade Array Jar Lesson

Learn how Claire Adams and Gabi Braud from Downtown Expeditionary Learning School use the Array Jar Routine to deepen students’ mathematical thinking. In this video, you’ll see how students engage in grouping, organizing, representing, and sharing their thinking—building both conceptual understanding and fluency. The Array Jar Routine supports students in developing key mathematical concepts, including: *Defining attributes of a rectangle *Connecting area and perimeter; relating area to multiplication and division *Understanding factor pairs through visual models *Seeing the relationship between multiplication and division *Applying the commutative, associative, and distributive properties of multiplication 🛠️ What is the Jars Routine? Jars is an easy-to-implement, individualized number sense routine and benchmark assessment system used in grades K–4. The routine is implemented weekly to build foundational, Common Core-aligned math skills, while the benchmark assessment is typically administered three times per year to monitor progress. Inspired by routines in curricula like Investigations and Illustrative Mathematics, Jars follows a LEDS lesson structure with a launch, student work time (grapple), and share/discussion. There are three types of Jars—Counting Jar, Money Jar, and Array Jar—each supporting a progression of skills from counting and one-to-one correspondence to skip counting, place value, area, and early multiplication. This routine addresses nearly 25% of the K–3 Common Core Math Standards and draws from research-backed practices like Counting Collections, Number Sense Routines, and Children’s Mathematics. 🚀 Ready to shift your school’s math culture?
