Digging Dinosaurs

Level A:
You are swimming underwater in a lake and you see dinosaur feet in the water. You don’t want to go to the surface of the lake in case they are not friendly dinosaurs.
How many dinosaurs are standing in the lake? Explain how you know. Use words and mathematical language to explain your solution..

Problem Restated: This basically states try to find all possible combinations and outcomes for this type of situation.

Process: The very first thing I did was to find out that there weren’t any dinosaurs with 1,3,5,6,7,8 feet. (Lincoln and John helped with that). Next, I figured that if there were only two-legged dinosaurs it would be four of them. 2+2+2+2=8. There could also be four-legged dinosaurs. In this case 4 x 2 = 8 found the number of dinosaurs. Last, there could be a combination of dinosaurs in the lake. A four-legged and two two-legged beasts.
Math:
2 four-legged dinosaurs make up eight feet or 4 + 4= 8
4 two-legged dinosaurs make eight feet or 2+2+2+2=8
1 four-legged dinosaurs and 2 two-legged dinosaurs make 8 feet or 4+2+2=8

Solution: A possible four two-legged, and two four-legged, as well as one four-legged and two two-legged. So 2,3,4 dinosaurs
