I work in quality at Learning Resources. My job is to check every deliverable before it reaches customers—roughly 200 unique items a year. Maybe 180, I'd have to check the log. I review specs, sample batches, packaging, and printed instructions. I also answer a lot of questions from teachers, school buyers, and parents. Here are the ones that keep coming up.

What exactly is Learning Resources?
Learning Resources is an educational toy and teaching supply brand with a 40+ year history as of 2025. We make hands-on math manipulatives, STEM kits, pretend play sets, measuring tools, classroom whiteboards, and educational toys. The typical users are teachers, school districts, and parents who want learning tools that feel like play.
Two things stand out. First, the products are designed for hands-on learning, not passive play. Second, we have quality standards for things you might not think about: does the cube snap stay after the 100th use? Is the ruler printing off by half a millimeter? Are the pieces in a 30-set actually 30? I've rejected batches for less. The National Council of Teachers of Mathematics has published guidance on the effective use of manipulatives, and that's a big part of why we obsess over the physical details.
What is the learning resources official website?
The learning resources official website is learningresources.com. As of January 2025, product pages include activity guides, safety documentation, classroom bundle details, and contact information. If you search and see a site like learning-resources.com with a hyphen, don't assume it's the same. The real domain is one word: learningresources.com.
I get why people type "learning-resources" with a hyphen; it's natural for a two-word name. But for school orders, you want the official channel. A good quick check: look for the customer service page, a physical address, and a history that matches the 40+ year story. If those are missing, be cautious.
What are pixel art learning resources?
Pixel art learning resources are grids that students color, square by square, to reveal a picture. They've become a staple in math centers because they combine coordinates, patterning, and fine motor work. You can find printable pixel art sheets online, but there are also physical versions that use hundred boards or linking cubes.
From a quality perspective, the most important thing is uniformity. If one square is a fraction of a millimeter bigger than another, the final image looks wonky. For printed resources, I recommend 300 DPI and a test copy before classroom use. For physical boards and cubes, we verify that every cell or cube is within tolerance. I'm not a curriculum designer, so I won't coach you on lesson plans. But I know that precise materials make precise lessons.
How to read a ruler in inches
On a standard 12-inch ruler, the longest line marks a whole inch. The next longest line is the half-inch mark. Then come quarter-inch marks, eighth-inch marks, and sixteenth-inch marks. The number of equal spaces between two inch marks tells you the denominator: two spaces means halves, four means quarters, eight means eighths, sixteen means sixteenths.
To read 1 3/8, start at the 1-inch mark and count three of the eighth-inch lines. It becomes automatic after a few tries. Our school rulers use clear numerals and high-contrast markings, because we don't want a student squinting. In Q1 2024, I caught a sample batch of tape measures with print registration off by almost 1/32 inch in the first inch. It looked fine at a glance, but it would have misled every measurement. We rejected the batch. A tool that teaches wrong is worse than no tool.
Do I need a CPM calculator?
A CPM calculator is one of those terms that depends on context. In the education conversations I hear, CPM sometimes means "calculations per minute"—a way to check math fluency. In marketing and logistics, CPM means cost per mille or cost per mile. These are completely different calculators, and confusing them will cause trouble.
If your goal is math fact fluency, you don't need a special CPM calculator. A basic primary calculator, a timer, and a simple record sheet work well. If you need cost-per-mile or ad campaign math, you need a different tool, and that's also fine—it's just outside Learning Resources' lane. I'd rather name the boundary than guess and give you a wrong tool.
What about a quadratic formula calculator?
Quadratic formula calculator? That's a no from us. Learning Resources does not make graphing calculators or algebra software. For solving ax² + bx + c = 0, a dedicated quadratic formula calculator or a good math app is probably more useful than anything in our catalog.
This is where I get honest about specialization. After 4 years of inspecting products, I've come to believe that specialists beat generalists. A brand that claims to cover everything usually ends up covering nothing well. We're good at hands-on PreK–8 learning tools. High school algebra technology isn't our strength, and I'd rather send you to a tool that fits the lesson than pretend otherwise.
Do STEM classroom bundles save time?
I have mixed feelings about bundles. On one hand, they make ordering easier and can reduce cost compared to buying separate items. On the other, a bundle with too many pieces can overwhelm a teacher. The best STEM classroom bundle isn't the largest one; it's the one that aligns with your curriculum.
From my seat, the quality bar is the same for bundles and single items. Every component gets counted, tested, and checked against safety standards like ASTM and CPSIA. If a 30-set of algebra tiles says 30, we count 30. If a measuring tool doesn't meet tolerance, it doesn't ship. If you choose a bundle that matches your actual lessons, the time savings are real. If you buy just because it's a bundle, it can become clutter.
