Cut and glue back to back A cards with number cards and B cards with ten frames. Students can draw for a partner and match their number cards with the matching ten frame.
When you need A and B teams students will turn their cards to find their A/B partner.
You can also use the chart to assign partners ahead of time or to record partner pairs after students find their partner.
Partners can switch daily or weekly according to your needs. The chart will allow you to keep track of partners if you keep partners together for more than one setting.
