'Biggest or smallest number to 20' for kindergarten

Kindergarten : Comparing numbers :
Biggest or smallest number: 1 to 20

In this topic you are asked to look at a group of four numbers and decide wich number is the biggest or the smallest. There are four numbers in each group, and the numbers can be as small as 1 and as big as 20. In the second question, you have the group of numbers :

6, 8, 4, 10

Start by looking at the number of digits for each number - one of the numbers has 2 digits (the number 10) but the other three only have one. We know that a 2 digit number like 10 or 12 is bigger than the biggest one digit number which is 9. So, if we are looking for the biggest number we can say straight away that 10 is the biggest number.

If we are looking for the smallest number, we need to compare the three numbers with only one digit, 6, 8 and 4. We know that 4 is a smaller number than 6 and 8 so 4 is the smallest number in the group. So we can say :

10 is the biggest number

4 is the smallest number


In another question from the topic you are shown the following group of numbers :

17, 7, 18, 11

So we use the same technique as last time and look at the number of digits for each number in that list. You will see that one of them has only one digit (the 7), so that must be the smallest number in the group.

There are three numbers in the group that have two digits and start with a 1, so compare their second digit. They are 7, 8 and 1. We know that 8 is bigger than 7 or 1 so the biggest number in the group has to be 18. So we can say :

7 is the smallest number

18 is the biggest number

With these interactive math lessons you will be learning "Biggest or smallest number to 20" from
Kindergarten / Comparing numbers in 3 easy steps. The math in our lessons consists of 6 questions that ask you to choose the biggest or smallest number in groups of numbers from 1 and 20.

How to use our tutorials to learn
'Biggest or smallest number to 20' for kindergarten

Introduction to the math topic

You start the tutorial with a lesson that introduces the math you will be learning. You will see a set of questions one at a time, and for each question you will see the written answer and also hear the answer to that question.

Repeat the question/answer by clicking on the brown speaker sign. Repeat the question/answer and expand the question graphic by clicking on the question box. Move between questions using the arrow buttons below the question. If there is additional information available for your chosen topic, the "i" button on the left upright bar will be brown on white. Click on the button to load the additional lesson information into the main interface.


Either / Or math lesson

This lesson moves on from the "Introduction" lesson and offers you two possible answers to each question. So, you will see a question then a voice will ask "Is this ... or is it ..." and you will have to choose which of the answers is the one that matches the question.

You choose an answer by clicking or tapping on one of the two answer boxes below the question. You can play the audio for each answer again by clicking on the speaker icon beside the written answer (if robot speech is available and enabled). The program will let you know each time whether you answered correctly. A star will light up red for a wrong answer or white/black for a correct answer.

This lesson asks you the questions in a random order compared to the introduction. At the end of the lesson, you can choose whether to repeat the lesson or move on to the next one.


What is it? math lesson

The final lesson of the tutorial shows you multiple possible answers for each question - you must choose the correct one. You are asked a question and below it are a list of two, three, or four possible written/numeric answers from this topic. Pressing the speaker icon will play the math audio for that answer.

For each picture, click on the answer that matches the question. The program will tell you whether you are right or not. As with the Either / Or activity a system of stars indicate your right and wrong answers. The What is it? lesson will show you all the questions you learned in the Introduction but in a random order.


When you complete the "What is it?" lesson, you can choose whether to go on to play some games with this topic, or whether you want to repeat some or all of the lesson activities in this tutorial. You should expect to get 80% of the answers correct in most of the activities before trying some of the Math games with this topic.
