Numbers: 1 to 10

Early Math · 10 lessons

Which number comes after 1?

  • 2
  • 3
  • 4
  • 5
Why:

A. 2 ✓

When we count in order, the numbers go 1, 2, 3, 4, 5... So 2 comes immediately after 1.

Why the others are wrong:
- B. 3 – This comes after 2, not after 1
- C. 4 – This comes much later in the sequence
- D. 5 – This is even further along; it comes after 1, 2, 3, and 4

Which number comes after 3?

  • 4
  • 5
  • 6
  • 2
Why:

A. 4 is correct because when we count in order (1, 2, 3, 4...), 4 comes immediately after 3.

B. 5 is wrong because 5 comes two numbers after 3, not right after.

C. 6 is wrong because 6 comes three numbers after 3.

D. 2 is wrong because 2 comes *before* 3, not after it.

How many fingers does this person have?

  • 10
  • 2
  • 9
  • 4
Why:

• A. 10 is correct — Most people have 10 fingers total (5 on each hand), which is the typical anatomical standard.

• B. 2 is wrong — This is far too few; only 2 fingers would indicate a severe injury or birth difference.

• C. 9 is wrong — This would mean the person is missing one finger, which isn't indicated in the question.

• D. 4 is wrong — This is only about one hand's worth, and doesn't account for all fingers.

Which number comes before 9?

  • 8
  • 10
  • 7
  • 6
Why:

A. 8 is correct because when we count in order (1, 2, 3, 4, 5, 6, 7, 8, 9...), 8 is the number that comes right before 9.

Why the others are wrong:
- B. 10 – This comes *after* 9, not before it
- C. 7 – This comes before 8, so it's two steps before 9, not the number right before it
- D. 6 – This is even further back in the counting order

Which number comes before 8?

  • 7
  • 6
  • 9
  • 10
Why:

A. 7 ✓

When counting in order (1, 2, 3, 4, 5, 6, 7, 8...), 7 is the number that comes immediately before 8.

Why the others are wrong:
- B. 6 – This comes before 7, so it's two numbers before 8, not one.
- C. 9 – This comes *after* 8, not before it.
- D. 10 – This comes well after 8, not before it.

How many days are there in a week?

  • 7
  • 5
  • 8
  • 6
Why:

Why A is correct:
A week has 7 days by definition—Monday through Sunday (or Sunday through Saturday). This is the standard calendar system used worldwide.

Why the others are wrong:
- B (5): There are only 5 weekdays (Monday–Friday), but weekends add 2 more days.
- C (8): No calendar system uses 8-day weeks.
- D (6): This doesn't match any standard week length.

How many toes does this person have?

  • 10
  • 8
  • 9
  • 3
Why:

• A (10) is correct – Most people are born with 10 toes (5 on each foot), which is the typical human anatomy.

• B (8) – This would only be true if the person had lost 2 toes due to injury or a medical condition, but nothing in the question suggests this.

• C (9) – This would mean missing just 1 toe, but again there's no indication of that here.

• D (3) – This is far too low and doesn't match normal human anatomy.

How many lemons are there on the tree?

  • 3
  • 4
  • 2
  • 5
Why:

# Explanation

A. 3 ✓
This is correct because counting the lemons visible on the tree in the image gives us exactly 3.

B. 4 ✗
This overcounts—there are only 3 lemons, not 4.

C. 2 ✗
This undercounts—you may have missed one lemon on the tree.

D. 5 ✗
This significantly overcounts the actual number present.

How many cups are there on the table

  • 7
  • 4
  • 6
  • 8
Why:

A. 7 is correct — This is the accurate count of cups visible on the table.

Why the others are wrong:
- B. 4 — Too low; you've undercounted by missing several cups.
- C. 6 — Close, but one cup was missed in the count.
- D. 8 — Too high; there's one fewer cup than this option suggests.

How many legs does this chair have?

  • 4
  • 2
  • 6
  • 8
Why:

A. 4 — Correct
A standard chair is designed with four legs to provide stable support and balance. This is the most common chair design you'll see in homes and offices.

B. 2 — Wrong
A chair with only 2 legs would be unstable and tip over easily. You'd need a person actively balancing it, not a functional piece of furniture.

C. 6 — Wrong
While some specialty furniture like certain stools might have more legs, a typical chair has 4, not 6.

D. 8 — Wrong
An 8-legged chair would be unusual and unnecessarily complicated for everyday use.
