MashupMath.com is an educational site offering free worksheets, puzzles, and video lessons for grades K-8. It's been online since 2015 and is run by a named team with contact information and social media profiles — all good signs for a legitimate resource site. We found no evidence this is a scam; its domain history is clean, and it passes Google's security checks. The main thing to watch for on any content site like this is how it handles your data: MashupMath has a privacy policy and terms of service, so you know what you're agreeing to. The only minor flag is that the page loads 26 external scripts, typical for analytics and embed features on Squarespace sites. If you're a teacher or parent looking for free math materials, there's no reason to avoid MashupMath based on our analysis. As with any free resource, just be mindful of cookies and tracking — but that's standard for the web.
In plain English
MashupMath.com is a trusted resource for K-8 math materials. It has been around for over a decade, its operators are transparent about who they are, and its security is solid. The only point worth noting is the large number of external scripts on the page — not a reason to avoid the site, but something to be aware of if you're concerned about tracking.
Where the score comes from
Solid overall security with valid HTTPS and clean threat reports. The high number of external scripts is a minor point to monitor but not unusual for a content site built on Squarespace.
Long-established domain registered for over a decade, with consistent ownership through NameCheap. This is a strong indicator of a legitimate, ongoing operation.
No blacklist issues and a Wayback history stretching back 10 years confirm a stable presence. The site's low traffic rank is typical for a niche educational resource.
Clear ownership and contact information, plus an active social media presence, show the operators are willing to be known. This is exactly what you want from an educational resource.
Privacy policy and terms of service are in place, covering the basics for a content-driven site. No EU-specific disclosure is needed for this US-based operation.
Hosted on a reputable platform (Squarespace) with proper email authentication. DMARC is in monitoring mode, which is acceptable for this site type, and DNSSEC is not enabled — common for many smaller sites.
