Kindergarten Counting Jar Lesson Overview

Learn how Maggie Waldner from Downtown Expeditionary Learning School uses the Money Jar Routine to support students in counting, organizing, representing, and sharing their thinking. The Counting Jar Routine supports students in developing key mathematical concepts, including: *Writing numbers *1-to-1 correspondence between number and quantity *Cardinality (understanding that the last number said represents the total) *Strategies for organization and efficient counting *Grouping in 2s, 5s, 10s, etc., to build fluency and pattern recognition *Representing quantities using base 10 models 🛠️ 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?
