Develop number sense while making connections to subitizing strategies with place value charts, place value mats, and value cards. I have developed “scaffolding cards” that provides an enrichment activity to the standard. These cards are useful in supporting students in small groups. I teach my students to work independently in math workshops. I have also included a formative assessment or “ticket out the door”. It only take minutes to assess a students’ mastery of the skill. Hope you enjoy the activity!
