Unit 1 — Place Value: Tens & Ones
Understanding 2-Digit Numbers · Comparing · Ordering
📚 Key Vocabulary
place valueThe value of a digit based on its position
onesThe right column — single units (1–9)
tensThe left column — groups of 10
digitAny number 0–9 used to write numbers
expanded formWriting a number as tens + ones: 47 = 40 + 7
compareFinding which number is greater or less
📊 Place Value Chart
TENS | ONES
47 = 4 tens + 7 ones = 40 + 7
TENS | ONES
63 = 6 tens + 3 ones = 60 + 3
🐊
Remember: the tens column is on the LEFT and tells you how many groups of 10. The ones column is on the RIGHT and tells you leftover singles. In 47: 4 tens = 40, 7 ones = 7!

📖 Read this passage:
Al Goes to the Pond
Al the Alligator woke up on a sunny Tuesday morning. He was very hungry. He decided to walk to the pond to find some fish for breakfast. On his way, he saw his friend Lumi the cat sitting on a rock.
"Good morning, Lumi!" said Al. "Would you like to come fishing with me?"
Lumi smiled. "I would love to! I know exactly where the biggest fish hide."
Together they walked to the pond. It was a great day for two friends to share an adventure.
A paragraph has a topic sentence, at least 2 detail sentences, and a closing sentence. Write a paragraph about your favorite animal.
Topic sentence (What animal? Why do you like it?)
Detail sentence 1 (Tell one fact about the animal)
Detail sentence 2 (Tell another interesting fact)
Closing sentence (Wrap it up!)
🐊
A great paragraph is like a sandwich 🥪 — the topic sentence is the top bread, the details are the filling, and the closing sentence is the bottom bread. Yum!
A food chain shows what animals eat. Arrows show energy flow: grass → rabbit → fox means the rabbit eats grass and the fox eats the rabbit.

How This Fits Into Lumi Academy
Mathematics works best when printable practice connects back to a real learning routine. Lumi pairs screen-based lessons with workbooks, coloring pages, report cards, attendance records, and certificates so families can keep both digital and paper evidence of learning.
Printables are especially useful for handwriting, quiet practice, portfolios, co-op days, review weeks, and end-of-year records. They also give kids a hands-on break after voice-guided or interactive lessons.
For homeschool documentation, the value is consistency: digital lesson history shows what was taught, while printable pages show practice artifacts families can save.
What kids experience
Kids start from their own profile and move through a guided session with a friendly on-screen teacher, short explanations, interactive questions, and instant encouragement. Younger learners can use tap choices and read-aloud prompts; older learners answer by tapping or typing, with quizzes and subject-specific checks.
What parents can verify
Parents can review lesson history, scores, subject progress, standards touched, attendance, and printable summaries. That turns daily learning into usable homeschool documentation instead of a vague "we did school today" memory.
Why it performs better at home
Lumi keeps lessons short, varied, and forgiving. If a child misses something, the app can explain again, offer a hint, log the result, and bring the concept back later. That makes the curriculum feel less like a worksheet stack and more like a steady learning loop.
Parent Planning Notes
For best results, treat Lumi as the daily spine of your homeschool routine. Most families do one focused session per child, then add reading aloud, outdoor time, projects, errands, co-op classes, or hands-on practice around it. The app covers the repeatable academic work while parents keep the flexibility that makes homeschooling valuable.
If you are comparing programs, look closely at whether the tool teaches the lesson, checks understanding, saves progress, and gives you printable records. A page can promise "complete curriculum," but the day-to-day mechanics are what determine whether parents can actually sustain it.
Quick Questions
Can Lumi be used as a core homeschool curriculum?
Yes. Lumi is designed as a full K-8 homeschool curriculum with math, reading and writing, science, social studies, quizzes, progress records, and printable parent documentation. Some families add field trips, library books, religious instruction, or co-op classes on top.
How does Lumi personalize learning?
Each learner has a separate profile with age range, grade level, subject progress, guide character, daily goal, and lesson history. The app uses completed lessons, missed questions, retry queues, and performance patterns to keep practice moving at a workable pace.
How should parents use this page?
Most families begin with the free trial, add each child profile, choose age range or grade level, then let Lumi run the daily lesson sequence while the parent dashboard tracks progress.
