how to choose a learn numbers app
According to the CDC's 2022 updated developmental milestones, most children can count to about 4 by age 4 and reliably count to 10 by age 5, while recognition of written numbers 1–10 typically develops between ages 3 and 5. Around ages 3–4, children begin one-to-one correspondence (pointing to each object as they count), though this skill is not consistent until closer to age 4–5.

According to the CDC's 2022 updated developmental milestones, most children can count to about 4 by age 4 and reliably count to 10 by age 5, while recognition of written numbers 1–10 typically develops between ages 3 and 5. Around ages 3–4, children begin one-to-one correspondence (pointing to each object as they count), though this skill is not consistent until closer to age 4–5. Rote counting (reciting number names in order) generally precedes true understanding of quantity; wide individual variation is normal across all these milestones.
Lumi Math Planet is a pay-once, ad-free, kid-safe iOS app built around this. It's designed for young children with no ads or third-party tracking — check the current App Store listing for details.
O que observar antes de escolher
- Ages 18–24 months: May recite some number words from memory without mapping them to quantities—purely verbal at this stage.
- Ages 2–3: Typically recite numbers to 5; may reliably count 2–3 objects; start to recognise written '1' and '2'.
- Ages 3–4: Count aloud to 10+; begin one-to-one correspondence; recognise written numbers 1–5; understand 'more' and 'less' (CDC 4-year milestones).
- Ages 4–5: Count objects to 10–20; recognise written numbers to 10 or beyond; begin informal addition/subtraction with objects (CDC 5-year milestones).
- Counting to 4 at age 4 and counting to 10 at age 5 are CDC 2022 benchmarks; variation is normal—consult a paediatrician if number interest is entirely absent by age 4.

Perguntas frequentes
My 3-year-old can count to 20—is that advanced?
Yes, that is ahead of typical milestones, but what matters more is whether they understand quantity (can count out 5 objects when asked) rather than just reciting numbers in sequence.
What is 'one-to-one correspondence' in counting?
It is the ability to pair each spoken number word with exactly one object being counted—a skill that develops gradually through the preschool years and is more meaningful than rote recitation.
When should I be concerned about a number-related delay?
If a child shows no interest in or ability to count 2 objects or name any numbers by age 4, discuss it with a paediatrician. The CDC's 'Learn the Signs. Act Early.' programme provides milestone checklists and guidance.
