Activity for early students. Limit distractions while organising for the day ahead.
On my pracs I have observed that students who come early either waste time outside or inside the classroom. As an attempt to warm up the students thinking skills for the day and smoothen transitions in the morning I created a brief workbook for students to record answers to conundrums. Before you open the classroom in the morning write up a conundrum on the board (The last page has suggestions and examples).
