'Biggest number: 20 to 50' for kindergarten

Kindergarten : Comparing numbers :
Choose the biggest number from 20 to 50

In this topic you are asked to look at a group of four numbers and decide wich number is the biggest. There are four numbers in each group, and the numbers can be as big as 50 or as small as 20. In the first question, you have the group of numbers :

34, 43, 33, 22

Start by looking at the first digit of each number - they are 3, 4, 3 and 2. So, if numbers have the same number of digits, then the number with the biggest first digit is the biggest number. We can see that we have a number with a 4 as the first digit, the 43, and the other numbers have smaller first digits so that has to be the biggest number in the group. So the biggest number in the list has to be :

43


In another question from the topic you are asked to find the biggest number from the following group of numbers :

44, 49, 21, 45

So we use the same technique as last time and look at the first digit of each number in that list. You will see that one of them is a 2, and the others are all bigger numbers, so that 21 cannot be the biggest number.

There are three numbers in the list that start with a 4, so compare their second digit. They are 4, 9 and 5. We know that 9 is bigger than 4 or 5 so the biggest number in the list has to be :

49

With these interactive math lessons you will be learning "Biggest number: 20 to 50" from
Kindergarten / Comparing numbers in 3 easy steps. The math in our lessons consists of 6 questions that ask you to choose the biggest number from groups of numbers between 20 and 50.

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.

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.

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.
