A student has 4 bags with 6 apples in each bag. Which multiplication sentence represents this situation?
A6 × 6 = 36, because there are 6 apples in each bag
B4 × 6 = 24, because there are 4 groups of 6
C4 × 4 = 16, because there are 4 bags
D6 × 4 = 24, and this is a different value from 4 × 6 = 24
The first number is the number of groups (4 bags), and the second number is the group size (6 apples each), so 4 × 6 = 24 is the correct sentence. Note that 6 × 4 also equals 24 due to the commutative property, but option D incorrectly claims the two expressions have different values — they produce the same total.
Question 2 Multiple Choice
Which of the following represents the same quantity as 3 × 5?
A3 + 5 = 8, using addition instead of multiplication
B5 + 5 + 5 = 15, adding 5 three times
C3 + 3 + 3 + 3 + 3 = 15, which represents a different grouping from 3 × 5
DOnly drawings of equal groups can represent multiplication — not repeated addition
3 × 5 means '3 groups of 5,' which is the same as 5 + 5 + 5 = 15. Option C (3 + 3 + 3 + 3 + 3) represents 5 × 3 — five groups of 3 — which equals 15 by the commutative property but describes a different physical grouping. Option B is the most direct match for '3 groups of 5.'
Question 3 True / False
3 × 7 and 7 × 3 have the same total, so they describe exactly the same physical arrangement of objects.
TTrue
FFalse
Answer: False
They have the same product (21), but describe different arrangements. 3 × 7 means 3 groups of 7; 7 × 3 means 7 groups of 3. Physically, these look different — 3 rows of 7 versus 7 rows of 3 — but the total number of objects is the same. This is the commutative property: the order of the factors does not change the product, even though the grouping looks different.
Question 4 True / False
Multiplication is just a faster way to write repeated addition for equal groups.
TTrue
FFalse
Answer: True
4 × 6 is exactly the same quantity as 6 + 6 + 6 + 6. The multiplication symbol is shorthand for 'groups of,' and the product equals the total you would get by adding the group size repeatedly. As numbers get larger, multiplication becomes much faster than writing out long repeated addition sentences.
Question 5 Short Answer
If you see a picture of 5 groups with 3 objects in each group, how would you write this as both a repeated addition sentence and a multiplication sentence?
The two sentences describe the same quantity in different forms. The first number in the multiplication sentence (5) is the number of groups; the second number (3) is the size of each group. Being able to translate freely between pictures, repeated addition, and multiplication sentences builds the understanding that multiplication is meaningful — not just a rule to memorize.
