The graph shows the number of seashells 3 students collected. Study the graph and answer the following.
- Who collected 14 seashells? Give the answer in number. (Eg 1)
- Which 2 students collected a total of 24 seashells? Give the answer in numbers. (Eg 1, 2)
- How many seashells must Elsa give to Kitty so that both of them would have the same number of seashells?
(a)
2 seashells → 1 circle
14 seashells → 14 ÷ 2 = 7 circles
(2) Riley had 7 circles so she collected 14 seashells.
(b)
Total number of circles represented by 24 seashells
= 24 ÷ 2
= 12
Number of circles that Kitty and Riley had
= 7 + 5
= 12
2 students who collected a total of 24 seashells are (2) Riley and (3) Kitty.
(c)
Difference in the number of circles between Elsa and Kitty
= 6 - 5
= 1
Number of seashells that Elsa must give to Kitty
= 1 ÷ 2 x 2
= 1
Answer(s): (a) 2; (b) 2, 3; (c) 1
