For $50, today's side deal gets you into the "Differentiation: Every Child Moves Ahead" NLC Instruction teachers' workshop (a $100 value). The workshop will take place on Oct. 5 from 9 a.m. to 3 p.m. at the Country Springs Hotel in Waukesha.

NLC (Next Level Challenge) Instruction helps strengthen schools by working with teachers and offering techniques to ensure that each of their pupils progresses. The "Differentiation: Every Child Moves Ahead" workshop will showcase new and useful strategies that teachers can implement the next time they step into a classroom. With NLC's differentiation method, you'll be able to craft a curriculum that improves students regardless of their skill level, because they'll have more avenues to reach their goals. The NLC staff uses a visual teaching approach to help workshop attendees grasp the concepts and the practices of differentiation. NLC creators Welda Simousek and Virginia Pickerell, who have a combined 75 years of public-school experience and have published two books, will help you develop a student program that's tailored to students’ strengths not their weaknesses. Sharpen your teaching skills and have the tools to better assist your students with today's Groupon to an NLC teachers' workshop.
