MULTIPLE
CHOICE
Kindergarten / Comparing numbers / Biggest smallest 1-20 / Biggest or smallest number 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 our quick math tests you will be revising "Biggest or smallest number to 20" in 2 simple steps. The math in our tests consists of 16 questions that ask you to choose the biggest or smallest number in groups of numbers from 1 and 20.
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 *
