Common Core Math Standards, Lesson by Lesson (K–5)

Every Kindergarten to Grade 5 math lesson in Steady Learners, in the order a child meets them, with the Common Core standards each one teaches. Use it to check coverage, find the lesson for a standard, or line the app up with your child’s class.

Does Steady Learners cover every Common Core math standard?

Almost all of them. Common Core has 148 math standards for Kindergarten to Grade 5. Steady Learners’ 144 math lessons fully teach 143 of them, teach 4 in part, and leave out 1, all listed below under “Which standards are only partly covered?”. Each lesson is listed with the standard codes it teaches. A few lessons teach a skill a grade early or late, to fit the order skills build on each other; those are marked.

How was this map made?

Each lesson was checked against the text of the Common Core State Standards for Mathematics (2010), standard by standard. A lesson is listed under a standard when its questions ask for that standard’s skill. The lessons are in the app’s own order within each grade. The map was last checked on November 10, 2026.

Which standards are only partly covered?

Standard	What it asks	In Steady Learners
K.CC.1	Count to 100 by ones and by tens	Partly: counting by ones to 20 (Count to 20) and by tens in Skip-Count to 1,000
K.CC.2	Count forward from any number	Partly: counting on within 20 (Counting On to 20)
1.NBT.1	Count, read and write numbers to 120	Partly: reading and building numbers with tens and ones (Tens & Ones), with no counting past 100 one by one
2.MD.6	Show sums and differences within 100 on a number line	Partly: a number line from 0 to 20 (Counting On to 20)
K.G.1	Describe where things are: above, below, beside, in front of, behind	Not taught as a lesson

What about English language arts?

Reading, phonics and grammar in Steady Learners are built around the Common Core English standards rather than mapped one lesson to one standard: phonics and spelling follow Reading: Foundational Skills (RF), the story questions follow Reading: Literature (RL), the 56 true books follow Reading: Informational Text (RI), and the 33 writing lessons follow Language (L). The Common Core guide for parents explains each strand.

Questions

How do I read a code like 3.NF.2?

The first part is the grade (K for Kindergarten), the middle is the domain (NF is Number and Operations, Fractions), and the last number is the standard. So 3.NF.2 is Grade 3’s second fractions standard: showing fractions on a number line.

Is any app “certified” for Common Core?

No organization certifies apps for Common Core. The useful check is whether an app lists which lesson teaches which standard, as this page does, so you can see the coverage yourself.

Can my child start at their grade instead of Kindergarten?

Yes. Each child starts at the grade that fits their age, and a parent can pick any lesson as the current one. Lessons move on once they’re mastered.
