TEMPTING TENTACLE PROBLEMS

(GRADES 1‐2)

REMEMBER! Soft coral polyps have eight tentacles.
Hard coral polyps in these problems have six tentacles.

For each problem, draw a picture to help you find the answer.
1. There was once a hard coral colony growing on a coral reef. A parrotfish came along and
bit off three tentacles from one of the hard coral polyps. How many tentacles did that
polyp have left?

2. Two soft coral polyps grew next to each other. How many tentacles did they
have altogether?

3. A crown-of-thorns sea star ate almost a whole hard coral colony. Only three hard coral pol-
yps were not eaten. How many tentacles did these three coral polyps have?

4. One day a soft coral grew four new coral polyps. How many tentacles did these new
coral polyps have altogether?
