Description
Exercise Name: Compare numbers of objects 1
Math Missions: Early math Math Mission
Types of Problems: 3

The Compare numbers of objects 1 exercise appears under the Early math Math Mission. This exercise helps students to better understand inequalities. They are tasked to use the concepts of lesser than and greater than correctly in a collection of problems.

Types of problems

There are three types of problems that show up in this exercise:

  1. Select the number above or below: This problem draws a number line and asks the student to select the answer choice that is either above or below a given number. Unlike an earlier problem, the number is not necessarily adjacent to the given number.

  2. Select which is larger and which is smaller: This problem asks the student to compare two numbers. They are to select the larger of the numbers in one question and the smaller of the two numbers in the other.

Strategies

These problems are straightforward and generally involve single digit numbers, making them fairly easy to attain both accuracy badges and speed badges.

  1. On the first problem type students do not need to wait for the picture to load since it is also written. They can just select the right answer after reading the question.
  2. On the second problem type, at least so far, the first answer is always the greater of the two number and the second answer is always the lesser of the two numbers.
  3. On the third question type, since the bins will fill and push towards the bottom of the screen it is wiser to place the larger numbers in their bins first.
  4. On the the third question type, all numbers go in bins. Therefore the two largest numbers will always go in the greater bin and the two smallest numbers will always go in the lesser bin.

Real-life Applications

  1. Knowing how to count is essential for learning algebra and the higher maths, and counting is used for almost everything humans do.
  2. The whole world evolves around numbers and counting.
