'Find the factors of numbers to 99' for 5th grade

Identify the factors of numbers up to 99

The factors of a number are the numbers that can be multiplied together to get that number. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12 because these numbers can be multiplied together to equal 12.

The factors of 6 are 1, 2, 3 and 6

The factors of 16 are 1, 2, 4, 8 and 16

The factors of 66 are 1, 2, 3, 6, 11, 22, 33 and 66

There is no single procedure for finding factors. All numbers have themselves and 1 as factors, but other factors you will need to work out for each number individually.

Knowing multiplication tables up to 10 can help in finding factors of larger numbers. For example, if you knows that 6 x 6 = 36, you can easily find that 1, 2, 3, 4, 6, 9, 12, 18, and 36 are factors of 36.

Some other numbers and their factors are:

The factors of 9 are 1, 3 and 9

The factors of 20 are 1, 2, 5, 10 and 20

The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48

The factors of 21 are 1, 3, 7 and 21

With these interactive math lessons you will be learning "Find the factors of numbers to 99" from
5th grade / Multiply + Divide in 3 easy steps. The math in our lessons consists of 6 questions that ask you to use times tables or otherwise to identify all the factors of numbers up to 99.

How to use our tutorials to learn
'Find the factors of numbers to 99' for 5th grade

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.
