"Nelson Mathematics 3" and "Math Focus Grade 3" are Nelson workbooks focused on the mathematics curriculum for Canadian third grade students. The senior author of both books is Dr. Marian Small, a Canadian expert on mathematics education.
"Nelson Mathematics 3" helps the students to connect previous knowledge with new information. Language has a vital part in explaining the lesson material, using real-life examples in several contexts for each new concept. On the other hand, "Math Focus Grade 3" contains as few words as possible to help the students to focus well. Every lesson is designed to help struggling students to address their problems with the new material.
