Division is much easier to understand when students can see how it connects to the math they already know. Math-U-See Delta builds on a strong foundation in multiplication to help students develop confidence and mastery in division.
In Delta, your child will learn single-digit and multi-digit division, including problems with remainders. Through visual models, place-value strategies, and hands-on learning, students discover the relationship between multiplication and division while developing a deeper understanding of both operations.
Additional topics include problem-solving with all four operations, introductory fraction concepts, Roman numerals, angles, geometric shapes, area, volume, money, and real-world applications. These lessons help students apply division skills in meaningful contexts while expanding their overall understanding of mathematics.
Like all Math-U-See levels, Delta follows a mastery-based approach, introducing one concept at a time and emphasizing understanding before moving on. Video instruction, visual demonstrations, and incremental practice help students build both confidence and accuracy as they progress.
Instructional videos and teacher resources are accessed through Math-U-See's Essential Plan. Each subscription includes 2 course credits, supports up to 5 student seats, and provides access to activated levels for one year.
Designed for students who have mastered multiplication, Math-U-See Delta provides a strong foundation in division while preparing learners for fractions, decimals, and more advanced mathematical concepts in future levels.

Math-U-See has transitioned from lifetime access to a one-year subscription for its digital resources, including instructional videos and the online teacher manual.
This new subscription provides digital access for two levels and up to five students. Depending on your family’s needs, this may offer more flexibility than the previous level-by-level lifetime access model.
One of the strengths of this plan is its flexibility. Your students are not locked into a single level. If a student finishes a level early or needs to go back and review an earlier one, you can swap a course credit to a different level right from your dashboard, up to once every 30 days. Because the plan includes two credits, a family with two students in different levels can often cover both with one subscription. When a student is ready to move up, you simply purchase the physical materials for the next level and swap the credit. As long as your subscription is active, there is no new subscription to buy to keep going.
