Math-U-See Delta teaches division as the inverse of multiplication beginning with single-digit division facts. Along with division, solving abstract and real-world problems using all four operations is introduced, as are short/long division with remainders, fractions and division, Roman numerals, dividing/multiplying/adding/subtracting US currency and standard units of measurement, and geometric shapes and angle measurements. The Math-U-See Delta Set includes all the required components: Math-U-See Integer Block Kit, Math-U-See Delta Student Workbook and Tests, Math-U-See Delta Instruction Manual and a one-year subscription card to the Individual Essential Plan which includes the online video lessons and other supplemental tools. For families who own the Integer Block Kit, we also offer the Delta Set (no Integer Blocks).
Please note: Digital access to the Math-U-See instructional videos is in transition. As of June 15th, 2026, the Digital Toolbox one-time, level specific online instruction with video is no longer available. The online component (available separately or in the curriculum packages) is now sold as the Individual Essential Plan Annual Access Card, which is redeemable for a one-year subscription to the Essential Plan. The Essential Plan includes 2 course credits (2 Math-U-See levels) as well as access to free resources for one year. Families may create 5 student accounts. With this new approach, families may activate one course and have flexibility for their child to move up to the next course if they finish early or to move back to a lower level for additional review as needed. Or if you have 2 students using Math-U-See, you may purchase one full package (with the Annual Access Card) for one student and then purchase the physical components (no Access Card) for the second student. If you have previously purchased a course with the Lifetime Access to the Digital Toolbox, it will continue to be available.
