Dino Tracks
- Math Word Problems
1.
Scientists estimate that the tracks in Morrison, CO were made 150 million years ago or:
150,000 years ago
150,000,000 years ago
150,000,000,000 years ago
2.
Scientists estimate dinosaur tracks as “?†millions of years ago (mya). Which of these trackway sites do scientist think is oldest:
Morrison, Colorado, USA: 150 mya
Holy Cross Mountains, Poland: 250 mya
Victoria, Australia: 115–100 mya
3.
Scientists estimate dinosaur tracks as “?†millions of years ago (mya). Which of these trackway sites do scientist think older than the other by at least 100,000,000 years:
Lesotho, Africa: 200 mya
Lima, Montana, USA: 95 mya
Hell Creek Formation, Wyoming, USA: 67 mya
4.
Scientists estimate that the trackways found in Lima, Montana, USA were made 95 million years ago and those found in Hell Creek Formation, Wyoming, USA were made 67 million years ago. That means that scientists believe that:
The tracks made in Montana were made approximately 28,000,000 years before the tracks made in Wyomin
The tracks made in Montana were made approximately 280,000 years before the tracks made in Wyoming.
The tracks made in Montana were made approximately 28,000,000,000 years before the tracks made in Wy
5.
Scientists estimate that the trackways found in Glen Rose, TX were made 110 million years ago and those found in Hadley, MA were made between 225 and 220 million years ago. That means that scientists believe that:
The tracks made in Hadley, MA could be half as old as the tracks made in Glen Rose, TX.
The tracks made in Hadley, MA could be twice as old as the tracks made in Glen Rose, TX.

If an ornithopod track measures 59 cm / 23 inches, that is approximately:
one foot
two feet
three feet or one yard
7.
If a theropod track measures 84 cm / 33 inches, that is almost:
one foot
two feet
three feet or one yard
8.
If a theropod track measures 8 cm, it is approximately:
3 inches
1 foot
1 yard
9.
If scientists estimate that every inch of footprint track (from heel to toe) equals a foot in length or height, then we can assume that the dinosaur that left a 3†track was about:
3 inches tall
1 foot tall
3 feet tall
10.
Scientists estimate that every inch of footprint track (from heel to toe) equals a foot in length or height. If a dinosaur left a 6 centimeter track and your father is 6 feet tall, then:
Your father is taller than the dinosaur was tall.
Your father is shorter than the dinosaur was tall.
