The activity in this free math video is good for developing mental math skills. Once the problems get bigger, children will be able to easily adapt this to larger numbers and add more quickly in their heads. Using the Cuisenaire Rods provides both a visual and tactile way to manipulate numbers instead of only relying on symbols. Young children, and children with dyslexia or dyscalculia often have difficulty fully understanding abstract symbols. Cuisenaire Rods help bridge the gap for them so that they can understand complex math concepts in spite of their learning difficulties.
