20 partners
Last week, the students practiced their 20 partners with a classmate by quizzing each other on their "rek n rek" tools. Each student made their own rek n rek with 20 beads, one group of 10 on the top and another group of 10 on the bottom. There are 5 red beads and 5 white beads in each group so it is easier for the students to identify 5+.
