Desk research from the maker's own pages. Not yet tried by us. Checked 2026-10-24.
A low-cost elementary math curriculum written by math teacher and homeschool parent Maria Miller. The Light Blue Series is a full program for grades K-8, and the Blue Series has topic books such as fractions, money or place value for filling gaps. Lessons are written to the student, so many children can work through them on their own, with an emphasis on understanding, mental math and word problems. Families buy printable PDFs or printed books, and there are free placement tests, videos and online practice.
Our take: A strong, affordable pick for homeschool families and parents filling math gaps who want paper-based, explanation-heavy lessons; kids who need games or color to stay motivated may balk.
Checked in a browser
A browser check on 2026-10-25: what loads, the ads and trackers we saw, and what a child meets first. Not a hands-on test.
| Child safety: 4 out of 5 | No ads shown; the page is a shop for parents with an email sign-up and links to homeschool review sites. |
|---|---|
| Data: 2 out of 5 | Google's ad network (doubleclick, googlesyndication) loaded with no ad shown, plus Google Tag Manager and an AWeber email tracker, before the cookie notice was answered. |
| Ease: 3 out of 5 | A sales page for parents, with an email form and a cookie notice; nothing here for a child to start. |
| Cost honesty: 3 out of 5 | Paid workbooks; two free sample books are offered in exchange for an email address. |
What we found
- Contacted 7 outside sites, including doubleclick.net, googlesyndication.com and aweber.com.
- Set 8 cookies, with third-party cookies from aweber.com and doubleclick.net.
- 0 ad frames appeared in 15 seconds.
- The main call to action is an email sign-up ('Count me in!') for two free books and newsletters.
From the test: A shop page for paid math workbooks meant for parents; the learning happens on paper, not on this site.

What's good
- Inexpensive full curriculum with no subscription
- Explanations written to the child, so it is nearly self-teaching
- Free placement tests to find gaps
- Works on paper with no screen time
Watch for
- Mostly black-and-white worktext pages, which some kids find dry
- Parents still need to check work and teach when a child is stuck
- Website juggles many sales banners, some out of date
Data and privacy
Browsing needs no personal details. Email sign-ups go to the Aweber mailing service, and the site uses basic Google Analytics. The policy was last updated in 2018 and says nothing about children or COPPA. Read the privacy policy.
Does it work?
No independent studies found. The maker's own claims only: it says the mastery approach builds number sense and readiness for algebra.
