[L2] Cracking the Code of Animal Lifespans
Practice
Lesson 2 to practice identifying factors and multiples of a number by exploring the lifespan of various animals. CC Standard: 4.OA.B.4 - Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite. Practice Lesson 2 Context: Lifespan of Animals Graphs: Dot plots, bar graphs Number of questions: 17 Difficulty level: Medium Estimated time: 20 min
Exploring Animal Lifespans From the long-living elephant to the short-lived otter, animals have fascinating lifespans, and behind each number is a secret waiting to be discovered. Scientists often break down an animal’s life into equal parts to study it better. To do that, we need to find all the numbers that divide evenly into the animal’s lifespan. These are called factors, and they help us understand how nature works in patterns! Click Next to proceed.
