A current parent guide to Cupertino, Sunnyvale, Santa Clara, Saratoga, and Los Altos

This South Bay math curriculum guide compares what Cupertino, Sunnyvale, Santa Clara, Saratoga, and Los Altos currently publish for elementary mathematics—and flags the details families still need to verify.

Sources reviewed July 29, 2026. However, curriculum adoptions, pilots, editions, and school-level supplements can change. Confirm the current classroom materials with your child’s teacher before purchasing matching practice.

Why This Guide Separates “Current,” “Pilot,” and “Historical”

District websites often leave old adoption lists online while schools roll out newer pilots or board-approved programs. Therefore, this guide uses current official district pages where possible and clearly labels older or incomplete evidence. It calls a textbook current only when an available official source supports that conclusion.

Cupertino Union: Go Math CA on the Current Published Page

Cupertino Union’s Mathematics page currently lists Go Math CA for grades K–5. The same page says the district adopted the program in March 2015 for six years. So, although the website still lists the title, the adoption record is old.

Use that information carefully: ask whether the 2026–27 classroom uses the same edition, an updated digital platform, or additional materials. The district’s math vision also emphasizes reasoning and communication, so a traditional-looking practice page is not the whole program.

Sunnyvale School District: Illustrative Mathematics K–5

Sunnyvale’s current curriculum page lists Illustrative Mathematics K–5 as the elementary core. Lessons often begin with a problem or representation and build toward an efficient strategy through student thinking and discussion.

At home, avoid jumping straight to a shortcut. Ask, “What do you notice?” “What does this drawing show?” and “Could another method work?” Those questions reinforce sense-making while still leaving the teacher’s lesson intact.

Santa Clara Unified: Laurelwood Confirms Origo

Laurelwood Elementary’s current mathematics page lists Origo Stepping Stones as the K–5 core curriculum and i-Ready Math as a support program. This is current school-level evidence, not proof that every Santa Clara Unified elementary school uses exactly the same configuration.

Ask your own school to name the core, assessment, and supplemental tools separately. As a result, families are less likely to mistake a digital support program for the main curriculum.

Saratoga Union: Eureka Math

Saratoga Union’s Math Resources page has a dedicated Eureka Math section for elementary families and links printables described as coming from “our math curriculum.” That resolves the earlier inconsistency: Eureka is the correct current family-facing account.

Eureka’s modules build ideas in sequence, so the most useful home question is often “Which earlier model does this lesson build on?” If a tape diagram or number bond is unfamiliar, reconnect the representation to the quantities before adding more practice.

Los Altos: Current Instructional Vision, No Named Core Title

Los Altos School District’s current mathematics page emphasizes inquiry, student thinking, connected ideas, reasoning, and collaboration. It does not identify one current elementary textbook title.

An older 2023–24 budget reference to enVision is not enough to call enVision the 2026–27 core. Families should ask for the active program, digital tools, and unit before buying aligned practice. The instructional vision is still useful: it signals that explanation and productive struggle matter alongside accurate procedures.

What South Bay Math Curriculum Programs Have in Common

The product names vary, but California districts are working within state standards and the California Mathematics Framework. Across programs, strong evidence of learning includes understanding a concept, carrying out procedures accurately, choosing a strategy for an unfamiliar problem, and explaining the reasoning.

• Concept: Can the child explain why the method works?
• Fluency: Are facts and procedures reliable enough to support harder work?
• Transfer: Can the child start when the numbers or context change?
• Communication: Can the child connect words, a model, and an equation?

Turn South Bay Math Curriculum Information into a Clear Next Step

A curriculum tells you what a grade should study. However, it does not show which prerequisite an individual child has missed or already mastered. ThinkZone’s personalized K–G8 math program starts with an adaptive assessment and builds a skill-level learning plan with tutor guidance and progress updates.

South Bay families can explore ThinkZone Cupertino or ThinkZone Sunnyvale. If you want to begin at home, use these simple math habits to observe how your child reasons before choosing extra materials.

Frequently Asked Questions

Does Cupertino Union still use Go Math?

The district’s current math page still lists Go Math CA for K–5, but it also shows a 2015 adoption date. Confirm the exact 2026–27 edition, platform, and supplemental materials with the school.

Is Saratoga using Eureka Math?

Yes, Saratoga Union’s current elementary family resources have a dedicated Eureka Math section and point to printables from the district’s math curriculum.

What math textbook does Los Altos use?

The current district mathematics page describes its instructional approach but does not name one core title. An older enVision reference is not sufficient to establish 2026–27 use.

2026–27 Local Curriculum Reference

Use this South Bay math curriculum reference as a starting point, not as enrollment or placement advice. Open the linked district source and confirm the current program, edition, grade, unit, and supplements with the school.
