MULTIPLE
CHOICE
1st grade / Comparing numbers / Biggest and smallest / Biggest & smallest number
In this topic you are asked to decide which number is the smallest and which is the biggest from a group of numbers. There are 6 numbers in each group, and each number is between 20 and 100. In the first question, you have the following group of numbers :
33, 60, 79, 54, 23, 65
Start by looking at the first digit of each number - they are 3, 6, 7, 5, 2 and 6. So, if two numbers have the same number of digits, then the number with the smaller first digit is the smaller number. We can see that we have a number with a first digit of 2, the number 23, and that the other numbers have bigger first digits so that number starting with 2 has to be the smallest number in the group.
Looking for the largest number, we can see that one of the numbers, 79, starts with 7, and there are no numbers starting with digits greater than 7, so in this group the smallest and biggest numbers are :
Smallest and biggest numbers = 23 and 79
In another question from the topic you are asked to find the smallest and biggest numbers from the following group of numbers :
45, 33, 31, 48, 46, 32
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 three of them have 3 as a first digit and three of them have 4, so one of those starting with a 3 must be the smallest number and one of those starting with a 4 must be the biggest number in the group.
There are three numbers in the list that start with a 3, so compare their second digit. They are 3, 1 and 2. We know that 1 is smaller than 2 or 3 so the smallest number in the list has to be 31.
We can follow a similar logic to find the biggest number from those numbers with a first digit of 4. So we can say that in this group the smallest and biggest numbers are :
Smallest and biggest numbers = 31 and 48
With our quick math tests you will be revising "Biggest & smallest number" in 2 simple steps. The math in our tests consists of 16 questions that ask you to choose the smallest & biggest number from groups of numbers between 20 and 100.
These math tests are designed to round off your learning experience here at Free Math Games by testing whether you can correctly recognize the math you have learned (in the multiple choice test) and that you can correctly enter the correct answers (in the writing test).
Make sure you have chosen the correct topic before starting! Although these tests are timed, try to relax and concentrate on getting the answers right at first - later you can try the tests again more quickly.
The two types of tests are:
Key features of our math tests include:
You should expect to score 8+ / 10 in each test before you select a new topic. It is a good idea to repeat the test for each topic you do after two weeks to "reinforce" the math for that topic
UXO * Duck shoot * The frog flies * Pong * Cat and mouse * The beetle and the bee
Rock fall * Four in a row * Sow grow * Choose or lose * Mix and match
This is a multiple choice activity similar to "What is it" in the Math lessons - you are shown a randomly selected question from the topic you are using. A selection of topic answers are displayed as a list. If you click/tap the speaker beside any answer you will hear the audio for that answer.
For each question, you must click on the answer that matches that question. If your answer is correct you will hear a bell and one star will be lit. The next question will be shown. If your answer is wrong, a box will open showing you what the correct answer was.
The test is timed, and the clock starts when you click the Start button. The clock stops when you click your final answer. At the end of your test a screen will tell you how many of the questions you got right and how long you took to complete the test.
The writing test checks whether you can type the correct answer using your keyboard. This test is also timed. You can do the test many times until you get a good score. To start the test, click on the "Writing test" sign in the navigation board, then click on the "Start the test" arrow.
A random problem from your selected topic is shown. Beneath the problem there is a white box into which you should type the answer. If you need a little help you can click on the "Help me" button for a tip. Only use the help if you really need to.
If you type the answer correctly your device will automatically light a star. If you have entered your answer and no star lights up, click on the tick or press Enter to check your answer. When you have tried all the questions, a screen will show you how many questions you answered correctly and how long it took.
* Try to score 8 out of 10 in both test before you choose a new topic *
* It is OK to do the tests many times if you need to *
