Mental Arithmetic Club: How do we start in our school

A starter kit for launching an after-school or lunchtime club that builds number sense and confidence. Sessions rotate through mental strategies (friendly numbers, compensation, breaking apart), estimation games, and quick challenges. Optional abacus/visual models, peer mini-lessons, and leveled badges keep motivation high. You’ll get a 6-week plan, printable challenge sheets, and tips for recruiting mentors and celebrating progress.
