After 25+ years of helping millions of students learn to read in schools all across the U.S., CEI is excited to offer a version of our flagship product designed specifically for use in the comfort of your own home. ELSO accelerates learning by focusing on the core of learning problems. “It’s like physical therapy for the brain.” – Parent of CEI student WHY IS ELSO FOR ME? See if any of the following describes the learning challenges that you or your family have been facing: - My child has a distinct learning disadvantage … maybe more than one. - My child is shy, bashful and withdrawn in a classroom setting. - My child is easily distracted by the actions of other students in the classroom. - My child is learning at a level far below that of fellow classmates. - My child is falling further and further behind in school. - English is a second language for my family. - Our hectic family schedule prevents me from helping in our children’s learning. - I need extra help in home-schooling my child. - Tutoring is not available through my child’s school. - Transportation costs and scheduling prevent me from traveling to tutoring centers. - Effective tutoring with proven results costs too much. - Being older than the other students who are being tutored embarrasses my child. - I, as an adult learner, personally experience some of the above. If you relate to even one of these statements, ELSO is the answer! HOW DOES ELSO WORK? The overwhelming strength of CEI programs is the ability to accelerate learning among the most at-risk students — those with the strongest of learning disadvantages. Just as our school-based learning solutions do, ELSO accelerates learning by focusing on the very core of learning problems … faulty sensory processing. All CEI products include activities that link visual, auditory, and motor, or “hands-on,” pathways in the brain, and ELSO is no exception. ELSO capitalizes on the brain’s ability to develop more fluid pathways for automatic recognition, retention, comprehension, and application of information. Throughout over 200 lessons, the program accelerates student learning by delivering automated, individualized, and differentiated instruction that addresses the most critical instructional processes:  INDIVIDUALIZATION — Self-paced instruction to meet the individual needs and skill level of each student  MULTISENSORY LEARNING — A series of exercises that stimulate the visual, auditory, and motor-kinesthetic pathways in the brain.  INTERACTIVE LEARNING — Five steps (external stimulation, mental processing, response, immediate feedback, and reinforcement) to keep learners engaged in activities SYSTEMATIC PHONICS INSTRUCTION — Focused instruction on how to link letters and sounds to form sound-symbol relationships and spelling patterns  LANGUAGE ENRICHMENT — Words, definitions, and sentences to aid in vocabulary development and retention and to provide background knowledge. PRACTICE AND REPETITION — A wide variety of activities to provide practice in several different contexts MASTERY — Instruction, practice, and review learners need to master the program’s content. HOW IS ELSO DIFFERENT FROM OTHER ONLINE READING PROGRAMS? * ELSO adheres to educational research regarding presentation, and CEI designs its programs to limit distractions. There are no busy screens, music, or animation. Exercises present simple illustrations that reinforce instructional goals. As a result, ELSO users can focus on the information presented. * Exercise introductions and feedback are available in English and Spanish, so learners with limited English skills can use the program immediately. * Nine fonts — including one designed for users with dyslexia — are available so learners may select the one that provides the best readability for their needs. We share in your goal of achieving remarkable results, and we are committed to helping you achieve academic, social and professional success! Learn more at www.ceilearning.com.

ABOUT Rocket Blades-- The Brain Safety Game CDC HEADS UP Rocket Blades is first-ever, mobile game app developed by the CDC, that teaches concussion safety to children ages 6 to 8. Through a futuristic world of galactic racing adventures, the game aims to help children learn the benefits of playing it safe and smart! Children must keep their players safe by avoiding obstacles that could lead to a concussion and make smart choices about resting players who have a concussion. When players are injured the game simulates concussion symptoms, making the screen blurry and play more challenging. At the end of each level, a doctor checks out all the players to make sure they are healthy to race, and their brains are rested and recharged. As children skate through levels they collect power gems. Power gems fuel up a spaceship that will blast off to Galactic City for a winner’s all-star dance party that is out of this world! As an added bonus, children can take a selfie and insert themselves into the dance party. BRAIN SAFETY EDUCATION AND CONCUSSION PREVENTION FEATURES CDC HEADS UP Rocket Blades helps children understand the following learning points: · hitting your head can cause brain injury (concussion); · you should tell your coach, parent, or another adult if you hit your head; · you should rest before returning to play and see a doctor if you hit your head; and · helmets alone cannot prevent concussions. ABOUT CDC HEADS UP The Centers for Disease Control and Prevention’s (CDC) HEADS UP campaign is a series of educational initiatives that all have a common goal: Protect kids and teens by raising awareness and informing action to improve prevention, recognition, and response to concussion and other serious brain injuries.
