I have been very happy with the math instruction my fourth graders have received at Mathnasium of Burlingame. I like that they start with an assessment of what the student needs to improve on, and then create an individualized plan so that every student has a different lesson plan. Each student works on the areas most needed. The staff to student ratio is about 1:3. And lastly, they make math fun and relevant. My sons enjoy going there. Two thumbs up.
