Now kids are getting another chance to learn math skills required by the state for grades K-8, plus Algebra 1. KERA TV is partnering with the Dallas Independent School District to broadcast math lessons created and presented by Dallas ISD teachers.
Here’s everything you need to know:
▸ Lessons will air from Monday, July 6, through Friday, August 7.
▸ They will be broadcast in 30-minute blocks on weekdays between noon and 2:30 p.m.
▸ The lessons for each grade level will be about 14 minutes long.
▸ The video classes will provide targeted, engaging instruction, with short breaks between the lessons.
▸ They will follow curriculum guidelines as set forth by Houghton Mifflin Harcourt for grades K-8th and McGraw Hill Education for Algebra I.
▸ Watch the lessons on KERA TV (Channel 13.1) or stream them at kera.org/live.
Why math? Dallas ISD decided to focus on math because researchers have projected that students could lose as much as a grade level in this crucial subject if the impact of COVID-19 closures is added to normal summer learning losses.
Need help? The math lessons are produced by Dallas ISD. If you have a question about a particular lesson, please contact STEM Math Director Stej Sanchez at email@example.com.
